The M27W201 is a low voltage 2 Mbit EPROM suitable for microprocessor systems requiring large data or program storage. It features low power consumption, high reliability, and easy programming.
The M27W201 is a 2 Mbit low‑voltage EPROM offered in UV‑erasable and one‑time‑programmable (OTP) versions. It operates from 2.7 V to 3.6 V and provides fast 70 ns access time, making it suitable for microprocessor systems that need large program storage.
The device is supplied in FDIP32W, PDIP32, PLCC32 and TSOP32 packages, features 2 000 V ESD protection, 200 mA latch‑up immunity, and includes a programmable electronic signature (Manufacturer Code 20h, Device Code 61h). Detailed electrical characteristics, timing diagrams and programming procedures are provided for both read and programming modes.
| Access Time | 70 ns (3.0 V‑3.6 V) / 80 ns (2.7 V‑3.6 V) |
|---|---|
| Standby Current | 15 µA max |
| Active Current (5 MHz) | 15 mA max |
| Supply Voltage (Voc) | 2.7 V to 3.6 V |
The standby current is specified as a maximum of 15 µA.
Programming uses Vpp = 12.75 V and Vcc = 6.25 V ± 0.25 V.
The access time is 70 ns when the supply voltage is between 3.0 V and 3.6 V.
