MX26C1000A
FUNCTIONAL DESCRIPTION
When the MX26C1000A is delivered, or it is erased, the chip has all 1000K bits in the "ONE", or HIGH state. "ZEROs" are loaded into the MX26C1000 through the procedure of programming. ERASE MODE The MX26C1000A is erased by an EPROM programmer or in-system. The device is set up in erase mode when the A9 = VPP = 12.75V are applied, with VCC = 5V and PGM = VIL.(Algorithm shown in Figure 3). Erase time is around 1sec. If the erase is not verified, an additional erase processes will be repeated for a maximum of 200 times.
PROGRAMMING MODE
PROGRAMMING ALGORITHM
The MX26C1000A is programmed by an EPROM programmer or on-board. The device is set up in the programming mode when the programming voltage VPP = 12.75V is applied, with VCC = 5 V and PGM = VIH (Algorithm shown in Figure 1). Programming is achieved by applying a single TTL low level 25us pulse to the PGM input after addresses and data lines are stable. If the data is not verified, additional pulses are applied for a maximum of 20 pulses. After the data is verified, one 25us pulse is applied to overprogram the byte so that program margin is assured. This process is repeated while sequencing through each address of the device. When programming is completed, the data at all the address is verified at VCC = VPP = 5V 10%. The VCC supply of the MXIC On-Board Programming Algorithm is designed to be 5V 10% particularly to faciliate the programming operation under the on-board application environment. But it can also be implemented in an industrial-standard EPROM programmer.
PROGRAM INHIBIT MODE Programming of multiple MX26C1000s in parallel with different data is also easily accomplished by using the Program Inhibit Mode. Except for CE and OE, all like inputs of the parallel MX26C1000 may be common. A TTL low-level program pulse applied to an MX26C1000A CE input with VPP = 12.75 0.25 V and PGM LOW will program that MX26C1000A. A high-level CE input inhibits the other MX26C1000A from being programmed.
PROGRAM VERIFY MODE Verification should be performed on the programmed bits to determine that they were correctly programmed. Verification should be performed with OE and CE, at VIL, PGM at VIH, and VPP at its programming voltage.
ERASE VERIFY MODE
COMPATIBILITY WITH MX27C1000 FAST PROGRAMMING ALGORITHM
Besides the On-Board Programming Algorithm, the Fast Programming Algorithm of MX27C1000 also applies to MX26C1000A. MXIC Fast Algorithm is the conventional EPROM programming algorithm and is available in industrial-standard EPROM programmers. A user of industrial-standard EPROM programmer can choose either of the algorithms base on his preference. The device is set up in the fast programming mode when the programming voltage VPP = 12.75V is applted, with VCC = 6.25V and PGM = VIL(or OE = VIH)(Algorithm is shown in Figure 2). The programming is achieved by applying a single TTL low level 25~100us pulse is applied for a maximum of 25 pulses. This process is repeated while sequencing through each address of the device. When the programming mode is completed, the data in all address is verified at VCC = VPP = 5V 10%.
Verification should be performed on the erased chip to determine that the whole chip(all bits) was correctly erased. Verification should be performed with OE and CE at VIL, PGM at VIH, and VCC = 5V, VPP = 12.5V
AUTO IDENTIFY MODE The auto identify mode allows the reading out of a binary code from an MTP that will identify its manufacturer and device type. This mode is intended for use by the programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional in the 25 5C ambient temperature range C that is required when programming the MX26C1000A. To activate this mode, the programming equipment must force 12.75V on address line A9 of the device. Two

MX26C1000A
identifier bytes may then be sequenced from the device outputs by toggling address line A0 from VIL to VIH. All other address lines must be held at VIL during auto identify mode. Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX26C1000A, these two identifier bytes are given in the Mode Select Table. All identifiers for the manufacturer and device codes will possess odd parity, with the MSB (DQ7) defined as the parity bit. This assures that all deselected memory devices are in their low-power standby mode and that the output pins are only active when data is desired from a particular memory device.
SYSTEM CONSIDERATIONS During the switch between active and standby conditions, transient current peaks are produced on the rising and falling edges of Chip Enable. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device. At a minimum, a 0.1 uF ceramic capacitor (high frequency, low inherent inductance) should be used on each device between VCC and GND to minimize transient effects. In addition, to overcome the voltage drop caused by the inductive effects of the printed circuit board traces on EPROM arrays, a 4.7 uF bulk electrolytic capacitor should be used between VCC and GND for each of the eight devices. The location of the capacitor should be close to where the power supply is connected to the array.
READ MODE The MX26C1000A has two control functions, both of which must be logically satisfied in order to obtain data at the outputs. Chip Enable (CE) is the power control and should be used for device selection. Output Enable (OE) is the output control and should be used to gate data to the output pins, independent of device selection. Assuming that addresses are stable, address access time (tACC) is equal to the delay from CE to output (tCE). Data is available at the outputs tOE after the falling edge of OE, assuming that CE has been LOW and addresses have been stable for at least tACC - tOE. STANDBY MODE The MX26C1000A has a CMOS standby mode which reduces the maximum VCC current to 100 uA. It is placed in CMOS standby when CE is at VCC 0.3 V. The MX26C1000A also has a TTL-standby mode which reduces the maximum VCC current to 1.5 mA. It is placed in TTL-standby when CE is at VIH. When in standby mode, the outputs are in a high-impedance state, independent of the OE input.
TWO-LINE OUTPUT CONTROL FUNCTION To accommodate multiple memory connections, a twoline control function is provided to allow for: 1. Low memory power dissipation, 2. Assurance that output bus contention will not occur. It is recommended that CE be decoded and used as the primary device-selecting function, while OE be made a common connection to all devices in the array and connected to the READ line from the system control bus.
