Product details
Overview
AT28C010-12EM/883 from Microchip Technology is a military-grade 1-Mbit (131,072 × 8) paged parallel EEPROM with 120 ns read access time, 10 ms maximum page write cycle, and single 5V ±10% supply operation. It features hardware and software data protection, DATA polling and toggle-bit write completion detection, and is designed for nonvolatile storage in avionics control modules requiring guaranteed operation from –55°C to +125°C.
For engineers reviewing the AT28C010-12EM/883 datasheet, AT28C010-12EM/883 pinout, AT28C010-12EM/883 application, or AT28C010-12EM/883 equivalent, this device serves as a drop-in replacement for legacy MIL-STD-883-compliant EEPROMs in high-reliability embedded systems where deterministic write timing, page-mode efficiency, and radiation-tolerant packaging are critical selection criteria.
Technical Context
The AT28C010-12EM/883 implements a paged architecture with a 128-byte internal latch, enabling simultaneous write of 1–128 bytes within a single 10 ms internal programming cycle. Its JEDEC-approved byte-wide interface uses standard CMOS/TTL-compatible signals and supports three distinct write modes: byte, page, and chip erase - all initiated via dedicated control pins (CE, OE, WE) without external timing components.
It integrates VCC sense circuitry that inhibits writes below 3.8 V, a 5 ms power-on delay timer, noise filtering on CE/WE inputs (<15 ns pulse rejection), and optional software data protection using a 3-byte command sequence (AAh/55h/A0h) to enable/disable write lock. The device also includes 128 bytes of dedicated identification memory accessible at 1FF80H–1FFFFH with A9 = 12 V.

Pinout & Package
AT28C010-12EM/883 is packaged in a 32-lead CLCC (Ceramic Leadless Chip Carrier) per MIL-STD-1835 C-12, with hermetically sealed ceramic body and gold-plated terminations for high-reliability solder joint integrity in thermal cycling environments.
| 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 provides DATA polling status; I/O6 provides toggle-bit write completion indication |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high-Z output when asserted high during standby |
| OE | Output Enable | Active-low output control; used with CE to prevent bus contention; required high during write operations |
| WE | Write Enable | Active-low write strobe; falling edge latches address/data; initiates byte/page programming sequences |
| VCC | Power Supply | +5 V ±10% main supply; powers core logic and I/O buffers; includes internal VCC sense for write inhibition |
| GND | Ground Reference | Signal and power return path; decoupling capacitor placement critical for noise immunity in high-speed read cycles |
| NC | No Connect | Pins 1 and 30 are unconnected; must remain floating per MIL-STD-883 test requirements |
Key Features
| Feature | Design Value |
|---|---|
| Page Write Architecture | 128-byte internal latch enables burst programming without CPU bus hold; reduces host-side timing overhead by >90% vs. byte-by-byte writes |
| Hardware Write Protection | VCC sense + 5 ms power-on delay + noise filtering eliminates false writes during brown-out or EMI transients in aircraft power systems |
| Software Data Protection | 3-byte unlock sequence (AAh/55h/A0h) prevents accidental overwrites; remains active through power cycles and resets |
| Write Completion Detection | Dual methods - DATA polling on I/O7 and toggle-bit on I/O6 - provide deterministic, non-blocking status feedback for real-time OS integration |
| Military Qualification | MIL-STD-883 Class B screening including temperature cycling, mechanical shock, and hermeticity testing ensures reliability in launch vibration and orbital vacuum |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15EM/883 | 150 ns read access time; otherwise identical electrical and functional specification | Suitable for systems where 30 ns slower access does not impact real-time deadlines (e.g., non-critical telemetry logging) | Select when cost sensitivity outweighs marginal timing margin; same pinout, same MIL-STD-883 qualification level |
| AT28C010-12DM/883 | Same 120 ns speed grade but in 32-lead CERDIP package instead of CLCC | Preferred for through-hole assembly in legacy repair programs or boards lacking CLCC reflow capability | Choose for backward compatibility with existing CERDIP footprints; identical timing and functionality, different mechanical form factor |
Compared with AT28C010-12EM/883, the -15EM/883 trades 30 ns read speed for lower unit cost in identical CLCC packaging, while the -12DM/883 retains full speed but shifts to CERDIP for manual assembly or legacy board reuse - neither requires PCB redesign, but only the -12EM/883 delivers optimal timing performance in surface-mount high-density layouts.

FAQ
What is the maximum page write size supported by the AT28C010-12EM/883?
The AT28C010-12EM/883 supports up to 128 bytes per page write operation. This is enabled by its internal 128-byte page register, which latches address and data on the first write strobe and accepts subsequent bytes within 150 µs (tBLC) of the prior byte. All bytes in a given page write must reside on the same 128-byte boundary defined by address bits A7–A16.
Does the AT28C010-12EM/883 require external high-voltage programming circuitry?
No, the AT28C010-12EM/883 operates from a single 5 V ±10% supply and requires no external high-voltage circuitry for standard byte or page writes. Only the optional chip erase mode requires 12 V applied to A9 - all other operations, including software data protection enable/disable, execute at 5 V.
How is write completion detected on the AT28C010-12EM/883?
The AT28C010-12EM/883 provides two independent hardware methods: DATA polling on I/O7 (complement of written data until completion, then true data) and toggle-bit detection on I/O6 (toggles between 0 and 1 during write, stabilizes upon completion). Both methods allow non-blocking status checking without halting the host processor.
What packaging options are available for the AT28C010-12EM/883?
The AT28C010-12EM/883 is specifically offered in the 32-lead CLCC (Ceramic Leadless Chip Carrier) package, marked with "EM/883" per MIL-STD-883 Class B requirements. Other variants like AT28C010-12DM/883 use CERDIP, but the -12EM/883 designation confirms the CLCC variant with full military screening and hermetic sealing.
Is software data protection enabled by default on the AT28C010-12EM/883?
No, software data protection (SDP) is disabled at factory shipment. It must be explicitly enabled by issuing the three-byte unlock sequence (AAh to 5555h, 55h to 2AAAh, A0h to 5555h). Once enabled, SDP remains active across power cycles until the disable sequence (AAh/55h/80h/AAh/20h/55h/2AAAh) is executed.
