Product details
Overview
M27C2001-10F6 from STMicroelectronics is a 2 Mbit (256K × 8) UV-erasable EPROM in a 32-pin FDIP32W ceramic frit-seal package with quartz window, supporting 55 ns access time, 5 V ±10% read supply, and 12.75 V ±0.25 V programming voltage. It operates in microprocessor-based embedded systems requiring nonvolatile program storage with field-erasable capability-e.g., industrial controller firmware or legacy test equipment boot code.
For engineers reviewing the M27C2001-10F6 datasheet, M27C2001-10F6 pinout, M27C2001-10F6 application, or M27C2001-10F6 equivalent, key selection criteria include UV erasure compatibility, two-line output control (E/G), TTL-level address/data interface, standby current of 100 µA, and PRESTO II programming algorithm support.
Technical Context
The M27C2001-10F6 implements a standard NMOS EPROM architecture with dual active-low control: Chip Enable (E) governs power state and device selection, while Output Enable (G) independently gates output drivers. Its logic diagram confirms full 18-bit address decoding (A0–A17) and 8-bit bidirectional data I/O (Q0–Q7) during programming.
It supports five distinct operating modes-Read, Standby, Program, Verify, and Electronic Signature-each defined by specific voltage and timing conditions on E, G, P, and VPP. The Electronic Signature mode uses A9 overvoltage (11.5–12.5 V) to return manufacturer code 20h and device code 61h on Q7–Q0, enabling automated programmer identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (262,144 × 8 organization), enabling full 8-bit microprocessor instruction/code storage without banking |
| Access Time | 55 ns max (tAVQV), compatible with 12–15 MHz Z80/8086 bus cycles in legacy systems |
| Read Supply | 5 V ±10%, eliminating need for dedicated 5.5 V regulator in standard TTL/CMOS systems |
| Programming Voltage | 12.75 V ±0.25 V on VPP, requiring isolated high-voltage supply but enabling single-pulse 100 µs/word writes |
| Standby Current | 100 µA at CMOS-level E high, reducing idle power in battery-backed or low-power hold states |
| UV Erase Dose | ≥15 W·s/cm² at 2537 Å wavelength, achievable in 15–20 min under commercial UV erasers at ≤2.5 cm distance |
| Input Capacitance | 6 pF (CIN), minimizing address bus loading in multi-chip memory arrays |
Pinout & Package
FDIP32W: 32-pin ceramic dual in-line package with UV-transparent quartz window, frit-seal construction, and 0.6-inch body width-designed for long-term data retention and repeatable UV erasure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit parallel address bus; fully decoded internally to select one of 262,144 bytes |
| Q0–Q7 | Data I/O | Bidirectional 8-bit data path: outputs during Read/Verify, inputs during Programming |
| E | Chip Enable | Active-low primary device select; drives device into 100 µA standby when high |
| G | Output Enable | Active-low output gate; enables Q0–Q7 drivers only when E is also low |
| P | Program Control | Active-low pulse input that initiates 100 µs programming cycle when E = low and VPP = 12.75 V |
| VPP | Programming Supply | 12.75 V ±0.25 V input required for programming; must be applied simultaneously with or after VCC |
| VCC | Supply Voltage | 5 V ±10% for Read; 6.25 V ±0.25 V for Programming-separate voltage domains prevent read corruption during write |
| VSS | Ground | Signal and power reference common to all inputs, outputs, and supplies |
| A9 | Electronic Signature Input | Overvoltage pin (11.5–12.5 V) used exclusively to enter Electronic Signature mode for auto-identification |
Key Features
| Feature | Design Value |
|---|---|
| Two-line output control (E + G) | Enables zero-bus-contention memory expansion: deselected chips enter standby (100 µA), not just high-Z |
| PRESTO II programming algorithm | Guarantees margin-safe programming in ≤26.5 s via automatic verify-in-margin-mode pulses-no overprogramming needed |
| Electronic Signature (20h/61h) | Allows programmers to auto-detect STMicroelectronics origin and M27C2001 identity without manual part selection |
| ECOPACK® compliance | Lead-free ceramic package meeting JEDEC JESD97 second-level interconnect marking requirements |
| UV erasure verification window | Integral quartz lid enables visual confirmation of erasure status and supports >100 erase/write cycles with proper dosage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar UV EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM27C2001-10DC | Same 2 Mbit ×8 organization and 55 ns speed, but AMD-manufactured with different electronic signature (01h/61h) and no ECOPACK® certification | Requires revalidation of UV erasure dose due to differing oxide thickness; not qualified for extended temperature industrial use | Select only if legacy AMD toolchain compatibility is mandatory and lead-free packaging is not required |
| M27C2001-12F6 | Identical silicon and pinout, but rated for 120 ns access time and specified for –40°C to 125°C operation | Higher standby current (1 mA vs. 100 µA) and slower timing limit use in high-speed or ultra-low-power designs | Choose for extended temperature range needs where 55 ns performance is unnecessary |
Compared with AM27C2001-10DC, M27C2001-10F6 offers guaranteed ECOPACK® compliance and tighter UV erasure specification; versus M27C2001-12F6, it delivers 2.2× faster access with 10× lower standby current-critical for real-time embedded responsiveness and energy-constrained deployments.

FAQ
What UV wavelength and exposure time are required to fully erase M27C2001-10F6?
Full erasure requires short-wave ultraviolet light at 2537 Å wavelength with a minimum integrated dose of 15 W·s/cm². Using a commercial UV eraser rated at 12,000 µW/cm², place the FDIP32W package within 2.5 cm of the lamp tubes for 15–20 minutes. Avoid fluorescent lighting exposure during storage, as ambient UV can cause partial erasure over months.
Can M27C2001-10F6 be programmed in-system using standard 5 V logic levels?
No. Programming requires VPP = 12.75 V ±0.25 V applied to the dedicated VPP pin, plus VCC = 6.25 V ±0.25 V-neither of which is compatible with standard 5 V logic. A separate high-voltage programming supply and level-shifting circuitry are mandatory. The device does not support in-system programming (ISP) via JTAG or serial interface.
Is the FDIP32W package hermetically sealed and moisture-resistant?
Yes. The FDIP32W uses ceramic frit-seal construction with a glass-to-metal seal around the quartz window, achieving hermeticity per MIL-STD-883 Method 1014. This prevents moisture ingress and ensures >10-year data retention at 85°C, making it suitable for harsh industrial and aerospace environments where plastic packages would outgas or delaminate.
Does M27C2001-10F6 support byte-level programming or only full-array writes?
It supports byte-level programming: each 8-bit word (addressed by A0–A17) can be individually programmed with a 100 µs pulse on the P pin while holding E low and applying valid data to Q0–Q7. The PRESTO II algorithm verifies each byte in margin mode before proceeding, enabling selective firmware patching without full array rewrites.
