Product details
Overview
AT28C010-15FM/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 automatic 1–128-byte page writes with internal latching and timer control, and delivers 300 µA CMOS standby current for low-power embedded systems requiring nonvolatile configuration storage in aerospace avionics.
For engineers reviewing the AT28C010-15FM/883 datasheet, AT28C010-15FM/883 pinout, AT28C010-15FM/883 application, or AT28C010-15FM/883 equivalent, this device serves as a drop-in replacement for legacy MIL-STD-883-compliant EEPROMs in high-reliability read/write memory subsystems where endurance (10,000–100,000 cycles), 10-year data retention, and hardware/software write protection are mandatory.
Technical Context
The AT28C010-15FM/883 implements a paged architecture with a 128-byte internal page register that latches address and data during write initiation, freeing the bus for concurrent operations. Its dual-line chip enable (CE) and output enable (OE) control enables precise bus contention management in multi-device systems.
Write completion detection is supported via DATA Polling on I/O7 (complement-to-data toggle) and Toggle Bit behavior on I/O6, both usable at any point during the ≤10 ms internal programming cycle. Hardware write inhibition includes VCC sense (<3.8 V), 5 ms power-on delay, and noise filtering (15 ns pulse rejection) on WE/CE inputs.
Key Specifications

|---|---|
| Memory Density | 1 Mbit (131,072 × 8) - provides full 16-bit address space with byte-level random access |
| Read Access Time | 150 ns max - meets timing requirements for 6.67 MHz synchronous bus interfaces |
| Page Write Cycle | ≤10 ms - enables burst programming of up to 128 bytes without external timing control |
| Supply Voltage | 5 V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for auxiliary supplies |
| Standby Current | 300 µA CMOS - reduces quiescent power in always-on mission-critical subsystems |
| Endurance | 10,000–100,000 write/erase cycles - supports field-updatable firmware and calibration tables |

Pinout & Package
AT28C010-15FM/883 is packaged in a 32-lead ceramic flatpack (MIL-STD-1835 MO-115 AA compliant) with 0.370" body width and 0.050" lead pitch. Pin 1 is marked by chamfered corner; pins are arranged in two parallel rows.
| 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 page writes |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface; I/O7 used for DATA Polling, I/O6 for Toggle Bit status indication |
| CE | Chip Enable | Active-low global select; must be held low for read/write; deassertion ≥50 ns required between reads |
| OE | Output Enable | Active-low output gate; controls data bus drive; used with CE for bus contention avoidance |
| WE | Write Enable | Active-low write strobe; falling edge latches address/data; initiates byte or page programming |
| VCC | Power Supply | +5 V ±10% main supply; powers core logic and I/O buffers; internal VCC sense prevents writes below 3.8 V |
| GND | Ground Reference | Signal and power return; decoupling capacitor placement near pin critical for noise immunity |
| NC (Pins 1, 30) | No Connect | Unbonded terminals; must remain unconnected per MIL-STD-883 requirement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15JC/883 | 32-lead CERDIP package (vs. flatpack); identical electrical specs and MIL-STD-883 screening | Better thermal dissipation in conduction-cooled chassis; requires different socket or solder footprint | Select for legacy CERDIP-based designs or when higher thermal mass improves reliability under transient load |
| DS2502-E48+T&R | 1-Wire serial interface; 1 kbit capacity; no parallel bus or page write capability | Used in asset tagging and simple parameter storage where bus count minimization outweighs speed needs | Choose only for ultra-low-pin-count systems where 150 ns read access and 128-byte page writes are not required |
Compared with AT28C010-15JC/883, the AT28C010-15FM/883 offers identical functionality in a lower-profile flatpack suitable for height-constrained avionics modules; compared with DS2502-E48+T&R, it delivers 1000× more density and parallel bus throughput but requires 19 signal lines instead of 2.

FAQ
What is the maximum operating temperature range for the AT28C010-15FM/883?
The AT28C010-15FM/883 is qualified for operation from −55°C to +125°C case temperature per MIL-STD-883 Method 1010. This full military temperature range is verified through temperature cycling, burn-in, and parametric testing at extremes, ensuring reliable performance in jet engine bays, satellite payloads, and nuclear control rooms where ambient conditions exceed commercial limits.
How does the AT28C010-15FM/883 implement write protection?
The AT28C010-15FM/883 implements dual-layer write protection: hardware-level inhibition via VCC sensing (blocks writes below 3.8 V), 5 ms power-on delay, and 15 ns noise filtering on WE/CE; plus software-level lock via three-byte command sequence (AAh/55h/A0h). Once enabled, the AT28C010-15FM/883 rejects all writes unless preceded by the same sequence, preserving configuration integrity during brownouts or EMI events.
Can the AT28C010-15FM/883 be used as a direct replacement for the AT28C010-15JC/883?
Yes, the AT28C010-15FM/883 is functionally and electrically identical to the AT28C010-15JC/883, differing only in package type (32-lead flatpack vs. CERDIP). Both share identical pinout, timing, voltage specs, and MIL-STD-883 screening. PCB layout changes are required due to mechanical form factor differences, but no logic or timing redesign is needed when substituting the AT28C010-15FM/883 into existing CERDIP footprints.
What is the purpose of the extra 128 bytes of EEPROM in the AT28C010-15FM/883?
The AT28C010-15FM/883 includes 128 bytes of dedicated identification EEPROM (addresses 1FF80H–1FFFFH) accessible by raising A9 to 12 V ±0.5 V. This area is used for device serialization, calibration data logging, or manufacturing trace codes-separate from main memory-and retains data independently under the same 10-year retention guarantee as the primary array.
Does the AT28C010-15FM/883 support chip erase functionality?
Yes, the AT28C010-15FM/883 supports optional software chip erase using a 6-byte command sequence documented in Microchip's application notes. Erase is performed at 12 V on A9 and clears the entire 131,072-word array. The AT28C010-15FM/883 also supports page erase via standard page write commands, enabling selective reprogramming without full-chip reset.
