Product details
Overview
AT28C010-12FM/883-341 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 AT28C010-12FM/883-341 datasheet, AT28C010-12FM/883-341 pinout, AT28C010-12FM/883-341 application, or AT28C010-12FM/883-341 equivalent, this device serves as a drop-in replacement for legacy parallel EEPROMs in avionics control modules, missile guidance firmware storage, and radiation-tolerant telemetry recorders where MIL-STD-883 Class B qualification and 10-year data retention are mandatory.
Technical Context
The AT28C010-12FM/883-341 implements a paged architecture with an internal 128-byte latch and autonomous control timer, enabling full-page writes without external timing circuitry. Its dual-line chip enable (CE) and output enable (OE) logic prevents bus contention during mixed-read/write operations in synchronous bus systems.
Hardware data protection includes VCC sense (write inhibit below 3.8 V), 5 ms power-on delay, and noise filtering on WE/CE inputs (rejects <15 ns pulses). Software data protection uses a three-byte command sequence (AAh/55h/A0h) to lock writes, with optional 128-byte identification memory accessible via A9 = 12 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8) - supports firmware image storage for microcontrollers with 8-bit parallel buses |
| Read Access Time | 120 ns - enables direct interface with 8-MHz Z80 or 68K-family processors without wait states |
| Page Write Cycle | ≤10 ms for 1–128 bytes - reduces system-level write latency versus byte-by-byte programming |
| Supply Voltage | 5 V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for auxiliary voltage regulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15FM/883 | 150 ns read access time; otherwise identical electrical and mechanical specs | Suitable for systems with relaxed timing budgets but same MIL-STD-883 qualification level | Select when 120 ns speed is not required to reduce cost or improve availability |
| DS2502+ (Maxim Integrated) | 1-Wire serial interface; 1 kbit capacity; no parallel bus or page write capability | Used in low-pin-count, low-bandwidth asset tagging-not suitable for high-speed firmware storage | Only consider for retrofitting legacy systems where board redesign permits serial interface migration |
Compared with AT28C010-12FM/883-341, the -15FM/883 offers identical military qualification and packaging but trades 30 ns of speed for broader sourcing; the DS2502+ lacks parallel bandwidth and endurance, making it unsuitable as a functional substitute in avionics or safety-critical control applications.

FAQ
What is the qualified temperature range for AT28C010-12FM/883-341?
The AT28C010-12FM/883-341 is fully qualified per MIL-STD-883 for operation from –55°C to +125°C case temperature. This includes temperature cycling, hermeticity testing, and burn-in screening to ensure reliability in extreme environmental conditions encountered in aerospace and defense platforms.
Does AT28C010-12FM/883-341 support true parallel page writes without external timing components?
Yes. The AT28C010-12FM/883-341 integrates an internal 128-byte latch and control timer that automatically executes page writes once address and data are latched. No external clock, delay circuit, or timing controller is required-only valid CE/WE/OE sequencing per the datasheet timing diagrams.
How is write protection implemented on AT28C010-12FM/883-341?
AT28C010-12FM/883-341 implements dual-layer write protection: hardware-based (VCC sense, 5 ms power-on delay, noise filtering on WE/CE) and software-based (3-byte command sequence AAh/55h/A0h). Both layers remain active through power cycles and prevent inadvertent writes during brownouts or EMI events.
Can AT28C010-12FM/883-341 be used as a direct replacement for older 27C256 EPROMs?
No. While AT28C010-12FM/883-341 shares JEDEC byte-wide pinout compatibility with 27C256, it is electrically erasable and requires no UV eraser. However, its WE/CE/OE timing, 5 V-only operation, and lack of VPP pin make it incompatible with EPROM sockets expecting 12.5 V programming voltage and different control logic.
What package type is used for AT28C010-12FM/883-341?
AT28C010-12FM/883-341 is packaged in a 32-lead CERDIP (Ceramic Dual Inline Package) per MIL-STD-1835 D-16 Config A, featuring hermetic sealing, gold-plated leads, and marking "12FM/883" to denote 120 ns speed grade and MIL-STD-883 qualification.
