Product details
Overview
M27C2001-10C6 from STMicroelectronics is a 2 Mbit (256K × 8) UV-erasable EPROM in PLCC32 package, featuring 55 ns access time, 5 V ±10% read supply, and 12.75 V ±0.25 V programming voltage. It supports two-line output control (E/G), electronic signature (0x20/0x61), and operates across –40°C to +85°C for embedded microprocessor program storage.
For engineers reviewing the M27C2001-10C6 datasheet, M27C2001-10C6 pinout, M27C2001-10C6 application, or M27C2001-10C6 equivalent, key selection criteria include UV erasability, 32-pin PLCC mechanical compatibility, TTL-level address/data interface, standby current of 100 µA, and PRESTO II programming algorithm support.
Technical Context
The M27C2001-10C6 implements a standard NMOS EPROM architecture with dual active-low control lines: Chip Enable (E) for device selection and Output Enable (G) for output gating. Its logic diagram confirms full 18-bit address decoding (A0–A17) and 8-bit bidirectional data I/O (Q0–Q7) during programming.
Programming requires precise voltage sequencing: VCC = 6.25 V ±0.25 V and VPP = 12.75 V ±0.25 V applied simultaneously, with P pulsed low while E is low. Erasure relies on UV exposure through the ceramic window in FDIP variants-but the -10C6 suffix denotes PLCC32, an OTP-capable package without window, confirming it is factory-configured as one-time programmable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Mbit (262,144 × 8 bits) - supports full 16-bit microprocessor code space with byte-wide access |
| Access Time | 55 ns - enables direct interface with 12–15 MHz Z80, 8086, or 68000-based systems without wait states |
| Read Supply | 5 V ±10% - compatible with legacy TTL/CMOS logic rails without regulation overhead |
| Standby Current | 100 µA - reduces system power in halted or sleep modes of industrial controllers |
| Programming Voltage | 12.75 V ±0.25 V - requires dedicated HV supply; not compatible with standard 5 V-only programmers |

| Q0–Q7 | Data I/O | Bi-directional 8-bit data path: outputs during read, inputs during programming |
| E | Chip Enable | Primary device select; CMOS-high places device in 100 µA standby (outputs Hi-Z) |
| G | Output Enable | Secondary output gate; allows shared data bus in multi-chip memory arrays |
| P | Program Control | Active-low pulse input that initiates 100 µs programming cycle when E = low and VPP = 12.75 V |
| VPP | Programming Supply | High-voltage input; must be stable at 12.75 V ±0.25 V during programming and verify cycles |
| VCC | Power Supply | 5 V ±10% for read; 6.25 V ±0.25 V for programming - requires separate regulation or switching |
| VSS | Ground | Reference node for all DC and AC timing; requires low-inductance 0.1 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Two-line output control (E/G) | Enables zero-power deselection of unaddressed devices in memory banks, eliminating bus contention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EPROM-based firmware storage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM27C2001-10DC | Same 2 Mbit ×8 organization, 55 ns access, but uses PDIP32 package with UV-erasable window; requires UV eraser | Supports firmware iteration during development; unsuitable for sealed final products | Select only if design phase requires multiple erase/program cycles and board layout accommodates UV exposure path |
| AT27C2001-10JC | Pin-compatible PLCC32 OTP EPROM; 55 ns access, but uses Atmel's proprietary programming algorithm and lacks electronic signature | No auto-ID capability in production programmers; requires manual algorithm selection per batch | Choose when ST supply chain constraints exist and programming infrastructure supports Atmel-specific command sequences |
Compared with AM27C2001-10DC and AT27C2001-10JC, the M27C2001-10C6 uniquely combines PLCC32 OTP form factor, ST's standardized electronic signature (0x20/0x61), and PRESTO II algorithm - enabling seamless integration into existing ST-programmer-based production lines without tooling changes.

FAQ
Is M27C2001-10C6 UV-erasable or one-time programmable?
M27C2001-10C6 is one-time programmable (OTP). The "C" in the suffix denotes PLCC32 packaging, which lacks the quartz window required for UV erasure. Unlike FDIP32W variants, this part is factory-configured for permanent programming only - erasure is physically impossible after initial programming.
What programming equipment is required for M27C2001-10C6?
M27C2001-10C6 requires a programmer supporting PRESTO II algorithm, capable of delivering 12.75 V ±0.25 V to VPP and 6.25 V ±0.25 V to VCC simultaneously during programming. Compatible tools include Data I/O PS-3000, BP Microsystems Model 7000, or Xeltek SuperPRO 5000 with ST-specific firmware v3.2+.
Can M27C2001-10C6 operate at 3.3 V?
No. M27C2001-10C6 is specified only for 5 V ±10% read operation and 6.25 V ±0.25 V programming. Its NMOS cell structure and TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) are incompatible with 3.3 V logic families. Interfacing to 3.3 V systems requires level-shifting buffers on all address, data, and control lines.
Does M27C2001-10C6 support page or burst programming?
No. M27C2001-10C6 supports only byte-level programming with 100 µs pulses per word. It does not implement page, sector, or burst programming modes. Each address location must be programmed individually, and PRESTO II verification occurs per-byte using margin-mode reads at reduced VCC levels.
