HM-6516 2K x 8 CMOS RAM March 1997 Features Description • Low Power Standby . . . . . . . . . . . . . . . . . . . 275µW Max The HM-6516 is a CMOS 2048 x 8 Static Random Access Memory. Extremely low power operation is achieved by the use of complementary MOS design techniques. This low power is further enhanced by the use of synchronous circuit techniques that keep the active (operating) power low, which also gives fast access times. The pinout of the HM-6516 is the popular 24 pin, 8-bit wide JEDEC standard, which allows easy memory board layouts, flexible enough to accommodate a variety of PROMs, RAMS, EPROMs, and ROMs. • Low Power Operation . . . . . . . . . . . . . 55mW/MHz Max • Fast Access Time. . . . . . . . . . . . . . . . . . 120/200ns Max • Industry Standard Pinout • Single Supply . . . . . . . . . . . . . . . . . . . . . . . . . . 5.0V VCC • TTL Compatible • Static Memory Cells The HM-6516 is ideally suited for use in microprocessor based systems. The byte wide organization simplifies the memory array design, and keeps operating power down to a minimum, because only one device is enabled at a time. The address latches allow very simple interfacing to recent generation microprocessors which employ a multiplexed address/data bus. The convenient output enable control also simplifies multiplexed bus interfacing by allowing the data outputs to be controlled independent of the chip enable. • High Output Drive • On-Chip Address Latches • Easy Microprocessor Interfacing Ordering Information 120ns HM1-6516B-9 8403607JA 8403607ZA 200ns TEMP.

READ CYCLE The address information is latched in the on-chip registers on the falling edge of E (T = 0), minimum address setup and hold time requirements must be met. After the required hold time, the addresses may change state without affecting device operation. During time (T = 1), the outputs become enabled but data is not valid until time (T = 2), W must remain high throughout the read cycle. After the data has been read, E may return high (T = 3). This will force the output buffers into a high impedance mode at time (T = 4). G is used to disable the output buffers when in a logical “1” state (T = -1, 0, 3, 4, 5). After (T = 4) time, the memory is ready for the next cycle.

WRITE CYCLE 6-5 2 3 4 5 HM-6516 The write cycle is initiated on the falling edge of E (T = 0), which latches the address information in the on-chip registers. If a write cycle is to be performed where the output is not to become active, G can be held high (inactive). TDVWH and TWHDX must be met for proper device operation regardless of G. If E and G fall before W falls (read mode), a possible bus conflict may exist. If E rises before W rises, reference data setup and hold times to the E rising edge. The write operation is terminated by the first rising edge of W (T = 2) or E (T = 3). After the minimum E high time (TEHEL), the next cycle may begin. If a series of consecutive write cycles are to be performed, the W line may be held low until all desired locations have been written. In this case, data setup and hold times must be referenced to the rising of E.
