Product details
Overview
M27C1001-15F1 from STMicroelectronics is a 1 Mbit (128K × 8) UV-erasable EPROM in FDIP32W ceramic window package, operating at 5V ±10%, with 150 ns access time, 30 mA active current at 5 MHz, and 100 µA standby current. It supports electronic signature (Manufacturer Code 20h, Device Code 05h) and requires 12.75 V ±0.25 V for programming at 100 µs/word.
For engineers reviewing the M27C1001-15F1 datasheet, M27C1001-15F1 pinout, M27C1001-15F1 application, or M27C1001-15F1 equivalent, key selection criteria include UV erasability, dual-line control (E/G), TTL-compatible inputs, 128K-word × 8-bit organization, and compatibility with legacy microprocessor systems requiring non-volatile program storage with field reprogrammability via UV exposure.
Technical Context
The M27C1001-15F1 implements a two-line output control architecture using Chip Enable (E) for power gating and Output Enable (G) for output bus arbitration-enabling low-power standby (100 µA) and preventing bus contention in multi-device memory arrays. Its UV-erasable silicon-gate CMOS process supports full array erasure via 2537 Å ultraviolet light (≥15 W·s/cm² dose).
Programming uses 12.75 V on VPP with 100 µs pulses per word, while read operation uses single 5V supply; A9 voltage must be 11.5–12.5 V during electronic signature mode to read manufacturer/device codes (20h/05h) on Q7–Q0. The FDIP32W package features a quartz window for UV exposure and frit-seal hermeticity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM27C1001-15DC | Same 1 Mbit × 8 organization, 150 ns access, 5 V supply, but uses PDIP32 package without UV window | OTP-only use case; no field erasure capability; suited for cost-sensitive, one-time-programmed systems | Select when UV erasability is unnecessary and plastic DIP packaging reduces BOM cost |
| MX27C1001-15PC | Pin-compatible 1 Mbit EPROM with identical FDIP32W package and 150 ns speed, but manufactured by Macronix | Same UV-erasable functionality and programming voltage; verified compatibility with ST's PRESTO II algorithm | Select for second-source assurance in long-lifecycle industrial programs where ST supply continuity is constrained |
Compared with AM27C1001-15DC, M27C1001-15F1 provides field-erasable flexibility at the cost of higher package unit price; versus MX27C1001-15PC, it offers identical functional behavior but with STMicroelectronics' qualified automotive-grade process and longer documented lifecycle support.

FAQ
What UV wavelength and exposure time are required to fully erase M27C1001-15F1?
The M27C1001-15F1 requires short-wave ultraviolet light at 2537 Å wavelength with a minimum integrated dose of 15 W·s/cm². Using a standard 12,000 µW/cm² UV lamp, full erasure takes 15–20 minutes at 2.5 cm distance. Direct sunlight may cause partial erasure in ~1 week; room fluorescent lighting can erase over ~3 years.
Can M27C1001-15F1 be programmed with standard 5 V logic levels?
No. Programming requires VPP = 12.75 V ±0.25 V applied to the VPP pin, while VCC must be set to 6.25 V ±0.25 V-not 5 V. Address and data inputs remain TTL-compatible (0–5 V), but the high-voltage VPP and precise VCC bias are mandatory for reliable 100 µs/word programming.
Is the FDIP32W package RoHS compliant?
The M27C1001-15F1 FDIP32W package predates RoHS legislation (2006) and contains leaded solder in its ceramic-to-metal seal. It is not RoHS compliant; STMicroelectronics discontinued RoHS conversion for this legacy UV EPROM family due to hermeticity and UV transmission requirements of the quartz window assembly.
How does the electronic signature mode function on M27C1001-15F1?
Electronic signature mode activates when A9 is biased to 11.5–12.5 V (VID) with VPP = VCC = 5 V. Toggling A0 between low and high reads Manufacturer Code (20h) on Q7–Q0 when A0 = low, then Device Code (05h) when A0 = high-enabling automatic algorithm selection in universal EPROM programmers.
