Description

The Am28F512A is a 512 Kbit Flash memory organized as 64 Kbytes of 8 bits each. AMD’s Flash memories offer the most cost-effective and reliable read/write non- volatile random access memory. It is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM programmers. The Am28F512A is erased when shipped from the factory. The standard Am28F512A offers access times as fast as 70 ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, It has separate chip enable (CE#) and output enable (OE#) controls.

Features

1. High performance
(1) 70 ns maximum access time

2. CMOS low power consumption
(1) 30 mA maximum active current
(2) 100 μA maximum standby current
(3) No data retention power consumption

3. Embedded Erase Electrical Bulk Chip-Erase
(1) Two seconds typical chip-erase including pre-programming

4. Embedded Program
(1) 4 μs typical byte-program including time-out
(2) One second typical chip program

5. Command register architecture for microprocessor/microcontroller compatible write interface
6. On-chip address and data latches

74LS189 Datasheet PDF – 64-Bit Random Access Memory – TI

Part Number: 74LS189

Function: 64-BIT RANDOM ACCESS MEMORY

Package: DIP 16 Pin

Manufacturer: Fairchild, TI

74ls189-random-access-memory

Description

The 74LS189 is a high speed 64-bit RAM orgainized as a 16-word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-state and are in the high impedance state whenever the Chip select (CS) input is HIGH. The outputs are active only in the Read mode and the output data is the complement of the stored data.

Pinout

Features

1. 3-State Ouputs For Data BUS Applications

2. Buffered Inputs Minimize Loading

3. Address Decoding ON-Chip

4. Diode Clamped Inputs Minimize Ringing
