S29C51004T/S29C51004B

4 MEGABIT (524,288 x 8 BIT)

5 VOLT CMOS FLASH MEMORY

Features

Description

The S29C51004T/S29C51004B is a high speed

524,288 x 8 bit CMOS flash memory. Writing or

erasing the device is done with a single 5 Volt

power supply. The device has separate chip enable

CE, write enable WE, and output enable OE

controls to eliminate bus contention.

The S29C51004T/S29C51004B offers a combi-

nation of: Boot Block with Sector Erase/Write

Mode. The end of write/erase cycle is detected by

■ 512Kx8-bit Organization

■ Address Access Time: 70, 90, 120 ns

■ Single 5V ± 10% Power Supply

■ Sector Erase Mode Operation

■ 16KB Boot Block (lockable)

■ 1K bytes per Sector, 512 Sectors

– Sector-Erase Cycle Time: 10ms (Max)

– Byte-Write Cycle Time: 35µs (Max)

■ Minimum 10,000 Erase-Program Cycles

■ Low power dissipation

DATA Polling of I/O or by the Toggle Bit I/O .

TheS29C51004T/S29C51004B features a

sector erase operation which allows each sector to

be erased and reprogrammed without affecting

data stored in other sectors. The device also

supports full chip erase.

Boot block architecture enables the device to

boot from a protected sector located either at the

top (S29C51004T) or the bottom (S29C51004B).

All inputs and outputs are CMOS and TTL

compatible.

– Active Read Current: 20mA (Typ)

– Active Program Current: 30mA (Typ)

– Standby Current: 100 A (Max)

■ Hardware Data Protection

■ Low V Program Inhibit Below 3.5V

■ Self-timed write/erase operations with end-of-cy-

cle detection

– DATA Polling

– Toggle Bit

■ CMOS and TTL Interface

■ Available in one versions

– S29C51004T (Top Boot Block)

The S29C51004T/S29C51004B is ideal for

applications that require updatable code and data

storage.

■ Packages:

– 32-pin Plastic DIP

– 32-pin TSOP-I

– 32-pin PLCC
