Product details
Overview
AT28C010-20DM/883 from Microchip Technology is a military-grade 1-Mbit (131,072 × 8) paged parallel EEPROM with 200 ns read access time, 10 ms maximum page write cycle, and single 5V ±10% supply operation. It features hardware/software data protection, DATA polling for write completion detection, and JEDEC-approved byte-wide pinout. Used in avionics control modules requiring nonvolatile storage with radiation-tolerant reliability.
For engineers reviewing the AT28C010-20DM/883 datasheet, AT28C010-20DM/883 pinout, AT28C010-20DM/883 application, or AT28C010-20DM/883 equivalent, key selection criteria include military temperature range (-55°C to +125°C), 10,000/100,000 endurance cycles, CMOS/TTL compatibility, 300 µA standby current, and 32-lead CERDIP packaging per MIL-STD-883 Class B screening.
Technical Context
The AT28C010-20DM/883 implements a paged architecture with a 128-byte internal page register, enabling simultaneous write of 1–128 bytes within a single internal programming period. Address latching occurs on the falling edge of CE or WE, and data latching on the first rising edge-decoupling bus activity during writes.
It supports three end-of-write detection methods: DATA polling (I/O7 complement toggle), Toggle Bit (I/O6 toggling), and software-controlled chip erase via 6-byte command sequence. Hardware protection includes VCC sense (<3.8 V inhibit), 5 ms power-on delay, and noise filtering for <15 ns pulses on CE/WE.

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15DM/883 | 150 ns read access time; identical pinout, endurance, and military screening | Better suited for systems requiring tighter read timing margins (e.g., high-speed DSP co-processors) | Select when 150 ns access is mandatory; otherwise AT28C010-20DM/883 offers optimal cost/performance balance for most MIL-SPEC platforms |
| AT28C010-25DM/883 | 250 ns read access time; same package, temperature range, and feature set | Targeted at lower-speed subsystems where power budget prioritizes ultra-low standby current over speed | Choose for battery-backed subsystems where 300 µA standby is critical and 250 ns latency is acceptable |
Compared with AT28C010-15DM/883 and AT28C010-25DM/883, the AT28C010-20DM/883 delivers the best trade-off between read performance (200 ns), power efficiency (300 µA standby), and broad compatibility across legacy MIL-STD-1553B, ARINC 429, and discrete logic-based avionics architectures.

FAQ
What is the maximum page write size supported by the AT28C010-20DM/883?
The AT28C010-20DM/883 supports page write operations of 1 to 128 bytes per internal programming 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 write initiation. This capability is implemented via an internal 128-byte page register that latches data independently of the host bus.
Does the AT28C010-20DM/883 require external high-voltage programming circuitry?
No, the AT28C010-20DM/883 operates from a single 5V ±10% supply for all read and write functions. High-voltage (12V ±0.5V) is required only for optional device identification area programming (addresses 1FF80h–1FFFFh) and chip erase-standard byte and page writes use standard 5V levels. The device includes built-in VCC sensing to inhibit writes below 3.8V.
How is write completion detected on the AT28C010-20DM/883?
Write completion on the AT28C010-20DM/883 can be detected using two hardware methods: DATA polling (monitoring I/O7 for complement-to-data transition) or Toggle Bit (observing I/O6 toggling state). Both methods operate without halting the host processor and are valid at any point during the write cycle. The internal control timer automatically terminates programming after ≤10 ms.
What packaging and screening standards apply to the AT28C010-20DM/883?
The AT28C010-20DM/883 is packaged in a 32-lead CERDIP (ceramic dual in-line package) and screened to MIL-STD-883 Class B requirements. Its marking "DM/883" indicates compliance with MIL-PRF-38535, including temperature cycling, burn-in, and hermeticity testing. The device carries the JAN prefix and 5962-38267 part number for full military traceability.
Can the AT28C010-20DM/883 be used as a direct replacement for UV-erasable EPROMs like the 27C010?
Yes-the AT28C010-20DM/883 uses a JEDEC-approved byte-wide pinout identical to the 27C010, enabling direct PCB replacement in legacy designs. However, unlike EPROMs, it requires no UV erasure window and supports in-system electrical reprogramming. System firmware must accommodate its write timing (10 ms page cycle) and DATA polling mechanism instead of fixed delay loops.
