M28256 datasheet

 

Description

The M28256 and M28256W devices consist of 32K x 8 bits of low power, parallel EEPROM, fabricated with STMicroelectronics’ proprietary double polysilicon CMOS technology.

The devices offer fast access time, with low power dissipation,and require a single voltage supply (5V or 3V, depending on the option chosen).

 

Features

1. FASTACCESSTIME :

(1) 90ns at 5V
(2) 120ns at 3V

2. SINGLE SUPPLY VOLTAGE:

(1) 5V± 10% for M-28256
(2) 2.7V to 3.6V for M-28256-xxW

3. LOWPOWER CONSUMPTION

4. FAST WRITE CYCLE:

(1) 64 Bytes Page Write Operation
(2) Byte or Page Write Cycle

Description

The K6X4008C1F families are fabricated by SAMSUNGs advanced full CMOS process technology. The families supports various operating temperature range and various package types for user flexibility of system design. The families also support low data retention voltage for battery backup operation with low data retention current.

CMOS Static RAM (SRAM) is a type of computer memory that uses Complementary Metal-Oxide-Semiconductor (CMOS) technology to store digital information.

Unlike dynamic RAM (DRAM) which needs to be constantly refreshed to maintain data, SRAM retains data as long as power is supplied to it. This makes SRAM faster and more reliable than DRAM, although it is also typically more expensive and requires more power.

Features

· Process Technology: Full CMOS
· Organization: 512Kx8
· Power Supply Voltage: 4.5~5.5V
· Low Data Retention Voltage: 2V(Min)
· Three state output and TTL compatible
