Product details
Overview
AT28C010-15UM/883 from Microchip Technology is a military-grade 1-Mbit (131,072 × 8) paged parallel EEPROM with 150 ns read access time, JEDEC-standard byte-wide pinout, and single 5V ±10% supply operation. It supports page write of 1–128 bytes in ≤10 ms, features hardware/software data protection, and is used in avionics control modules requiring nonvolatile configuration storage under extended temperature cycling.
For engineers reviewing the AT28C010-15UM/883 datasheet, AT28C010-15UM/883 pinout, AT28C010-15UM/883 application, or AT28C010-15UM/883 equivalent, key selection criteria include its MIL-STD-883 Class B qualification, 128-byte internal page latch, DATA Polling/Toggle Bit write completion detection, -55°C to +125°C operating range, and compatibility with legacy 8-bit parallel bus architectures in defense electronics.
Technical Context
The AT28C010-15UM/883 implements a CMOS-based EEPROM architecture with integrated address/data latches for page mode operation, internal control timer for autonomous write execution, and dual-line chip enable (CE)/output enable (OE) logic to prevent bus contention. Its block diagram confirms separate X/Y decoders, I/O buffers, and identification memory region at 1FF80H–1FFFFH.
It operates in three primary modes: Read (CE=low, OE=low, WE=high), Byte Write (CE or WE low with OE high), and Page Write (sequential 1–128-byte load within 150 µs intervals on same A7–A16 page). Write inhibition is enforced via VCC sense (<3.8V), 5 ms power-on delay, noise filtering (<15 ns pulses rejected), and software data protection (SDP) using 3-byte command sequences.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15JM/883 | Identical electrical specs but 32-lead CERDIP package (vs. 30-pin PGA); different thermal resistance and mounting method | Suitable for through-hole board assembly; less vibration-resistant than PGA in high-G launch environments | Select for legacy CERDIP socket compatibility or when PGA footprint unavailable |
| DS2502-E48+T&R | 1-Wire serial interface (vs. parallel); 1 kbit capacity; no page write; 100k-cycle endurance | Used in distributed sensor nodes where wiring count reduction outweighs speed and density needs | Select only for space-constrained, low-pin-count designs accepting slower write throughput |
Compared with AT28C010-15UM/883, the AT28C010-15JM/883 offers identical functionality in a through-hole ceramic package ideal for manual repair, while DS2502-E48+T&R trades parallel speed and density for minimal interconnect-neither matches the AT28C010-15UM/883's combination of military PGA ruggedness, 1-Mbit density, and 128-byte page efficiency.

FAQ
What does the "/883" suffix indicate in AT28C010-15UM/883?
The "/883" suffix certifies that the AT28C010-15UM/883 has been tested and qualified per MIL-STD-883, including mechanical shock, thermal cycling, and burn-in screening. This ensures compliance with Class B reliability requirements for military and aerospace deployments, distinguishing it from commercial-grade variants like AT28C010-15UM.
How does DATA Polling work on the AT28C010-15UM/883?
During a write cycle, reading the last written byte from the AT28C010-15UM/883 returns the complement of the data on I/O7 until completion. Once valid data appears on I/O7, the write is finished. This allows host firmware to poll I/O7 without halting other operations, enabling efficient use of CPU cycles during programming.
Can the AT28C010-15UM/883 be used as a direct replacement for older 27C1024 EPROMs?
No-the AT28C010-15UM/883 is an EEPROM with write capability and different timing; while pinout matches JEDEC standards, its WE control, write-enable logic, and lack of UV-erasure make it incompatible with EPROM-only sockets. It replaces 28Cxxx EEPROMs-not one-time-programmable EPROMs.
What is the purpose of the 128-byte device identification memory in AT28C010-15UM/883?
The AT28C010-15UM/883 reserves addresses 1FF80H–1FFFFH as user-accessible EEPROM for serialization, calibration data, or firmware version tracking. Access requires raising A9 to 12V ±0.5V, providing secure, field-updatable identity storage independent of main memory array.
Does the AT28C010-15UM/883 support chip erase, and how is it performed?
Yes-the AT28C010-15UM/883 supports optional software chip erase using a 6-byte command sequence. It requires applying 12.0V ±0.5V to A9 and issuing specific address/data patterns; full details are in Microchip Application Note AN20006311, section 5.10.
