Intel l,1DMAaCE OaFOO G3GiJA400O a 2Kx8 2048 x 8-BIT STATIC RAM • Fully Static Operation; No Clocks, • Two Line Control, CE Controls Power- Refresh or Latches Down, OE Controls Output Buffers — Eliminates Bus Contention ■ EPROM Compatible Pinout ■ 150 ns Maximum Access Time ■ Industry Standard 244-Pin Package ■ Auto Power-Down The Intel® 2K x 8 is a 16,384-bit static RAM organized as 2048 words by 8 bits. It employs fully static cir- cuitry which eliminates the need for cllocks, refresh, or address setup and hold times. The auto power- down feature cuts power consumption when the device is disabled. The 24-pin industry standard pinout allows easy upgrades to 4Kx 8 static RAMs and compatibility to the 2732 4K x 8 and 2764 8K x 8 EPROMs in 28-pin sites. The two line control simplifies decoding and elimi- nates any possibility of bus contention.

Compatible Pinouts 1-73 intel® 2732 32K (4K x 8) UV ERASABLE PROM • Fast Access Time: • Output Enable for MCS•85TM and MCS• — 390 ns Max. 2732.4 86TM Compatibility — 450 ns Max. 2732 — 550 ns Max. 2732.6 • Low Power Dissipation: • industry Standard Pinout — JEDEC — 150 mA Max. Active Current Approved — 35 mA Max Standby Current • Pin Compatible to Intel's EPROM Family: 2716, 2732A, 2764 • Single +5V ± 5% Power Supply The Intel® 2732 is a 32,768-bit ultraviolet erasable and electrically programmable read-only memory (EPROM). The 2732 operates from a single 5-volt power supply, has a standby mode, and features an output enable control. The total pro- gramming time for all bits is three and a half minutes. The 2732 family with an access time up to 390 ns enhances microprocessor system performance. This family, in conjunction with the 250 ns 2732A family, solves the problem of WAIT states due to slow memories. An important 2732 feature is the separate output control, Output Enable (OE) from the Chip Enable control (CE). The OE control eliminates bus contention in multiiple bus microprocessor systems. Intel's Application Note AP-72 describes the microprocessor system implementation of the OE and CE controls on Intel's 2716 and 2732 EPROMs. AP-72 is available from Intel's Literature Department. The 2732 has a standby mode which reduces the power dissipation without increasing access time. The maximum active current is 150 mA, while the maximum standby current is only 35 mA, a 75% savings. The standby mode is achieved by applying a TTL-high signal to the CI_' input. 2732 2732A MODE SELECTION PIN CONFIGURATION PIN CONFIGURATION PINS CE OE/Vpp VCC OUTPUTS (9-11,13-171 24 24 VCc MODE 081 (201 124) 23 23 Al Read VIL VIL +5 DOUT 22 22 Ag Standby VIH Don't Care +5 High Z 21 21 A11 20 20 ÓE/Vrr Program VIL Vpp +5 DIN 19 113 4,0 Program Verify VIL VIL +5 DOUT 18 10 CÉ Program Inhibit VIH Vpp +5 High Z 17 17 g 16 16 O, 15 1!i Oy 14 14 04 13 13 o, BLOCK DIAGRAM DATA OUTPUTS VCC ~ 00-07 GND 1 ' 1 ' ..
