Semiconductor MSM514260C/CSL
DESCRIPTION
This MSM514260C/CSL version: Jan. 1998 Previous version: May 1997
262,144-Word 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
The MSM514260C/CSL is a 262,144-word 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM514260C/CSL achieves high integration, high-speed operation, and low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/ single-layer metal CMOS process. The MSM514260C/CSL is available in a 40-pin plastic SOJ or 44/ 40-pin plastic TSOP. The MSM514260CSL (the self-refresh version) is specially designed for lowerpower applications.
FEATURES
* 262,144-word 16-bit configuration * Single 5 V power supply, 10% tolerance * Input : TTL compatible, low input capacitance * Output : TTL compatible, 3-state * Refresh : 512 cycles/8 ms, 512 cycles/128 ms (SL version) * Fast page mode, read modify write capability * CAS before RAS refresh, hidden refresh, RAS-only refresh capability * CAS before RAS self-refresh capability (SL version) * Package options: 40-pin 400 mil plastic SOJ (SOJ40-P-400-1.27) (Product : MSM514260C/CSL-xxJS) 44/40-pin 400 mil plastic TSOP (TSOPII44/40-P-400-0.80-K) (Product : MSM514260C/CSL-xxTS-K) xx indicates speed rank.

Semiconductor Notes:
MSM514260C/CSL
1. A start-up delay of 200 s is required after power-up, followed by a minimum of eight initialization cycles (RAS-only refresh or CAS before RAS refresh) before proper device operation is achieved. 2. The AC characteristics assume tT = 5 ns. 3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times (tT) are measured between VIH and VIL. 4. This parameter is measured with a load circuit equivalent to 2 TTL loads and 100 pF. 5. Operation within the tRCD (Max.) limit ensures that tRAC (Max.) can be met. tRCD (Max.) is specified as a reference point only. If tRCD is greater than the specified tRCD (Max.) limit, then the access time is controlled by tCAC. 6. Operation within the tRAD (Max.) limit ensures that tRAC (Max.) can be met. tRAD (Max.) is specified as a reference point only. If tRAD is greater than the specified tRAD (Max.) limit, then the access time is controlled by tAA. 7. tOFF (Max.) and tOEZ (Max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. 8. tRCH or tRRH must be satisfied for a read cycle. 9. tWCS, tCWD, tRWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS tWCS (Min.), then the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If tCWD tCWD (Min.) , tRWD tRWD (Min.), tAWD tAWD (Min.) and tCPWD tCPWD (Min.), then the cycle is a read modify write cycle and data out will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, then the condition of the data out (at access time) is indeterminate. 10. These parameters are referenced to the UCAS and LCAS, leading edges in an early write cycle, and to the WE leading edge in an OE control write cycle, or a read modify write cycle. 11. These parameters are determined by the falling edge of either UCAS or LCAS, whichever is earlier. 12. These parameters are determined by the rising edge of either UCAS or LCAS, whichever is later. 13. tCWL should be satisfied by both UCAS and LCAS. 14. tCP is determined by the time both UCAS and LCAS are high. 15. Only SL version.
