概要

Description

M27C1001-10B1 is a 1-megabit ultraviolet-erasable EPROM (non-volatile memory) with a 128K × 8 organization. Key points:
- Capacity/organization: 1 Mbit total, 128K bytes × 8 data bus (A0–A16 address lines; DQ0–DQ7 data I/O).
- Speed/packaging: Speed grade -10 (approx. 120 ns access); typically in a 28-pin DIP or SOP.
- Power and programming: Vcc ~5V; Vpp ~12–13V required for programming; /CE, /OE, /WE control signals.
- Erase/write: Contents can be erased only with UV light (windows), then reprogrammed with an EPROM programmer.
- Features: Non-volatile, widely used for firmware/BIOS storage in older systems and microcontroller apps.
- Notes: Not a flash memory; requires UV exposure to erase and separate programming voltages. Packaging variants (including industrial/temperature grades) may vary by vendor.
Common vendors: ST, AMD, Macronix, etc. It’s largely superseded by flash today, but still found in legacy hardware.

Features

Key features of M27C1001-10B1:
- Memory: 1 Mbit total (128K × 8) organization
- Interface: 8-bit data I/O; 17 address lines (A0–A16)
- Package: 28-pin DIP (also available in other 28-pin packages)
- Control pins: CE#, OE#, WE# for parallel access
- Power: Vcc = 4.5–5.5 V; Vpp programming voltage (~12.5 V)
- Type: UV-erasable EPROM (windowed); erasable with UV light and reprogrammable
- Speed grade: -10 (typical access in the 120–150 ns range, depending on lot)
- Non-volatile: data retained after power-off
- Temperature options: industrial/commercial variants available (check specific lot)
- Applications: firmware/code storage, boot ROMs, microcontroller support
Note: Programming requires a dedicated EPROM programmer; erase with UV light before reprogramming.

Package

28-pin DIP plastic package (DIP-28).

Pinout

- Pin count: 32 pins (DIP32/PLCC32)
- Function: 1 Mbit parallel EPROM (non-volatile program memory), typically 128K × 8. It uses address lines A0–A16, data I/O lines D0–D7, control inputs CE, OE, WE, and power pins Vcc/Vss. The -10B1 suffix denotes speed grade and package variant.

Manufacturer

Manufacturer: STMicroelectronics (ST).
What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and other electronic components, including memory devices.

Application

- Firmware storage for embedded controllers (boot code, application firmware)
- BIOS/firmware storage in legacy PCs and consumer electronics (set-top boxes, printers)
- Automotive and industrial control, telecom equipment requiring fixed ROM
- Prototyping, development and test benches (erasable PROM for iterative programming)
Note: M27C1001-10B1 is a 1-Mbit UV-EPROM (128K × 8), 10 ns speed, package B1.
