R1LV0408CSP-5SI datasheet

Description

The R1LV0408CSP-5SI is a 4-Mbit static RAM organized 512-kword ×8-bit. R1LV0408C-I Series has realized higher density, higher performance and low power consumption by employing CMOS process technology (6-transistor memory cell). The R1LV0408C-I Series offers low power standby power dissipation; therefore, it is suitable for battery backup systems. It has packaged in 32-pin SOP, 32-pin TSOP II and 32-pin STSOP.

M27C4001 Datasheet PDF – 4 Mbit (512Kb x 8), EPROM

Posted on by pinout

Part Number: M27C4001

Function: 4 Mbit (512Kb x 8) UV EPROM and OTP EPROM

Package: DIP 32, PLCC 32, SOP 32 Pin type

Manufacturer: STMicroelectronics

Pinouts:

M27C4001 datasheet

 

Description

The M27C4001 is a 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited for microprocessor systems requiring
large programs and is organised as 524,288 by 8 bits.

The FDIP32W (window ceramic frit-seal package) has a transparent lid which allows the
user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure.

Features

1. 5V ± 10% supply voltage in Read operation

2. Access time : 35ns

3. Low power consumption:
(1) Active Current 30mA at 5MHz
(2) Standby Current 100µA

4. Programming voltage: 12.75V ± 0.25V

5. Programming time: 100µs/Word

6. Electronic signature
(1) Manufacturer Code: 20h
(2) Device Code: 41h
