Product details
Overview
AT28C010E-12FM/883 from Microchip Technology is a military-grade 1-Mbit (131,072 × 8) paged parallel EEPROM with 120 ns read access time, single 5V ±10% supply operation, and JEDEC-approved byte-wide pinout. It supports page write cycles of up to 128 bytes in ≤10 ms and delivers 300 µA CMOS standby current for low-power embedded systems requiring nonvolatile storage in harsh environments.
For engineers reviewing the AT28C010E-12FM/883 datasheet, AT28C010E-12FM/883 pinout, AT28C010E-12FM/883 application, or AT28C010E-12FM/883 equivalent, this device serves as a drop-in replacement for legacy MIL-STD-883-compliant EEPROMs in avionics control modules, radar memory buffers, and secure firmware storage where data retention ≥10 years and endurance ≥10,000 write cycles are mandatory.
Technical Context
The AT28C010E-12FM/883 implements a paged architecture with an internal 128-byte latch and autonomous control timer, enabling simultaneous loading of 1–128 bytes before initiating self-timed internal programming. Its dual-line chip enable (CE) and output enable (OE) logic prevents bus contention during read operations in multiprocessor systems.
Hardware data protection includes VCC sense (write inhibit below 3.8 V), 5 ms power-on delay, noise filtering on WE/CE inputs (<15 ns pulses rejected), and software data protection (SDP) via three-byte command sequences at addresses 5555H/2AAAH/5555H. Device identification uses dedicated 128-byte sector accessible via A9 = 12 V.

Pinout & Package
AT28C010E-12FM/883 is packaged in a 32-lead CERDIP (Ceramic Dual In-line Package) with hermetic sealing and MIL-STD-883 screening. Pin 1 is index corner marked; pins 1 and 30 are NC; pin 16 is GND; pin 32 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 131,072-word addressing; A7–A16 define page boundaries for 128-byte writes |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS/TTL-compatible 8-bit data path; I/O7 provides DATA Polling feedback; I/O6 provides Toggle Bit status |
| CE | Chip Enable | Active-low chip select; must be stable ≥50 ns before OE assertion to avoid read corruption |
| OE | Output Enable | Active-low output gate; high-Z state when deasserted prevents bus contention in shared-memory architectures |
| WE | Write Enable | Active-low write strobe; falling edge latches address; rising edge latches data for byte or page mode |
| GND / VCC | Power Terminals | Pin 16 (GND) and Pin 32 (VCC) provide decoupling reference; requires local 0.1 µF ceramic capacitor |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-12JC | Commercial grade (0°C to +70°C), same pinout and AC timing, no MIL-883 screening or burn-in | Lacks radiation tolerance and extended temperature validation; unsuitable for flight hardware | Select only for ground-test fixtures or non-safety-critical lab equipment |
| MX28F1000PC-12 | Intel-compatible pinout, 120 ns access, but requires 12 V for program/erase; no built-in SDP or DATA Polling | Needs external high-voltage generator and polling firmware; higher system BOM cost | Choose only if legacy Intel 28Fxxx ecosystem compatibility is mandatory |
Compared with AT28C010E-12FM/883, the AT28C010-12JC sacrifices military reliability for lower cost in benign environments, while the MX28F1000PC-12 adds design complexity with external HV support and lacks integrated write-status signaling-making AT28C010E-12FM/883 the optimal choice for new MIL-SPEC designs requiring zero-additional-component integration.

FAQ
What is the maximum page write size supported by the AT28C010E-12FM/883?
The AT28C010E-12FM/883 supports page write operations of 1 to 128 bytes per cycle. All bytes must reside on the same 128-byte page defined by address bits A7–A16, and successive bytes must be loaded within 150 µs (tBLC) to avoid premature internal programming initiation. This capability enables efficient firmware patching without full-chip erase overhead.
Does the AT28C010E-12FM/883 require external high-voltage programming circuitry?
No, the AT28C010E-12FM/883 operates entirely from a single 5 V ±10% supply for both read and write functions. High-voltage (12 V) is required only for accessing the optional 128-byte device identification sector (addresses 1FF80H–1FFFFH) via A9 pin-standard program/erase operations use only VCC.
How is write completion detected on the AT28C010E-12FM/883 without polling delays?
The AT28C010E-12FM/883 provides two hardware-assisted methods: DATA Polling (I/O7 returns complement of last written byte until write completes) and Toggle Bit (I/O6 toggles between 0 and 1 during active programming). Both allow immediate status checking without fixed-time delays, reducing CPU overhead in real-time systems.
What packaging and screening level does the AT28C010E-12FM/883 meet?
The AT28C010E-12FM/883 is supplied in a 32-lead hermetically sealed CERDIP package and qualified to MIL-PRF-38535 Class B standards, including temperature cycling, steady-state life test, and burn-in. The "/883" suffix confirms compliance with MIL-STD-883 Test Methods for microcircuits used in defense applications.
Can the AT28C010E-12FM/883 be used as a direct replacement for older 27C010 EPROMs?
Yes-the AT28C010E-12FM/883 features JEDEC-approved byte-wide pinout identical to 27C010 EPROMs, allowing socket-level replacement. Unlike EPROMs, it requires no UV erasure and supports in-system reprogramming via standard 5 V logic levels, eliminating EPROM programmers and UV erasers from the production flow.
