Product details
Overview
AT28C010E-12EM/883 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 automatic 1–128-byte page writes with 10 ms max cycle time and delivers 300 µA CMOS standby current for low-power embedded systems in aerospace and defense avionics.
For engineers reviewing the AT28C010E-12EM/883 datasheet, AT28C010E-12EM/883 pinout, AT28C010E-12EM/883 application, or AT28C010E-12EM/883 equivalent, this device serves as a drop-in replacement for legacy MIL-STD-883-compliant EEPROMs requiring high-reliability nonvolatile storage with hardware/software data protection, DATA polling, and toggle-bit write completion detection.
Technical Context
The AT28C010E-12EM/883 implements a paged architecture with a 128-byte internal latch, enabling burst writes without external timing control. Its dual-line chip enable (CE) and output enable (OE) logic allows flexible bus contention management in multiprocessor systems.
It integrates VCC sense circuitry (write inhibit below 3.8 V), 5 ms power-on delay, noise filtering on WE/CE inputs (<15 ns pulse rejection), and optional software data protection using a 3-byte command sequence (AAh/55h/A0h) to prevent inadvertent writes during power transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 131,072 × 8 bits (1 Mbit); supports full memory mapping without bank switching |
| Read access time | 120 ns maximum; enables direct interface with 8-MHz Z80 or 10-MHz 8086-style buses |
| Page write cycle | ≤10 ms; internal timer eliminates need for external write-strobe generation |
| Supply voltage | 5 V ±10%; compatible with standard TTL/CMOS logic rails and MIL-STD-704 aircraft power |
| Standby current | 300 µA (CMOS); reduces system-level quiescent power in always-on mission-critical modules |
| Endurance | 10,000 write/erase cycles; validated per MIL-STD-883 Method 1037 |

Pinout & Package
AT28C010E-12EM/883 is supplied in a 32-lead CLCC (Ceramic Leadless Chip Carrier) package with 0.050" pitch, hermetically sealed per MIL-STD-883, and marked "AT28C010E-12EM/883" with military date code YQyywwl format.
| 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 writes |
| I/O0–I/O7 | Bidirectional data bus | CMOS/TTL-compatible 8-bit parallel interface; I/O7 provides DATA polling; I/O6 provides toggle-bit status |
| CE | Chip Enable | Active-low device select; must be stable before address setup for reliable read/write initiation |
| OE | Output Enable | Active-low output gate; used with CE to manage bus contention in shared-memory architectures |
| WE | Write Enable | Active-low write strobe; falling edge latches address/data; supports both byte and page write modes |
| VCC | Power supply | +5 V ±10% input; includes internal VCC sense for automatic write inhibition during brownout |
| GND | Ground reference | Signal and power return; requires low-inductance connection to minimize noise coupling during page writes |
| NC | No Connect | Pins 1 and 30 are unconnected; must remain floating per MIL-STD-883 requirement |
Key Features
| Feature | Design Value |
|---|---|
| Hardware data protection | VCC sense + 5 ms power-on delay + noise-filtered WE/CE inputs prevent spurious writes during power-up/down transients |
| Software data protection | User-configurable via AAh/55h/A0h command sequence; remains active across power cycles until explicitly disabled |
| DATA Polling | I/O7 returns complement of last written byte during write; enables deterministic host polling without fixed delays |
| Toggle Bit detection | I/O6 toggles during write; provides asynchronous write-complete signal independent of address/data bus activity |
| Device identification area | 128 bytes at 1FF80H–1FFFFH accessible with A9 = 12 V; used for traceability, calibration data, or firmware version stamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-12DM/883 | Same die, 32-lead CERDIP package; 0.600" width; higher thermal resistance than CLCC | Suitable for through-hole PCB assembly; less suitable for high-vibration environments due to lead fatigue risk | Select when legacy board layout mandates DIP footprint or when thermal cycling exceeds CLCC qualification limits |
| DS2502-E48+T&R | 1-Wire serial interface; 1 kbit capacity; no parallel bus support; factory-programmed 48-bit ID | Used for simple device authentication or calibration data tagging-not for firmware/code storage | Choose only for low-pin-count, point-to-point identification tasks where bus bandwidth and density are secondary |
Compared with AT28C010E-12EM/883, the AT28C010-12DM/883 offers identical electrical performance but different mechanical reliability in shock/vibe; the DS2502-E48+T&R trades parallel speed and capacity for extreme pin count reduction and built-in serialization-neither is a pin-compatible substitute.

FAQ
What is the maximum operating temperature range for the AT28C010E-12EM/883?
The AT28C010E-12EM/883 is rated for operation from −55°C to +125°C case temperature, fully compliant with MIL-STD-883 Test Method 1010.7. This range is verified across all AC and DC parameters in the official Microchip datasheet DS20006311A, including read access time, write cycle time, and standby current, making it suitable for engine-mounted or space-constrained avionics enclosures where ambient temperatures exceed commercial-grade limits.
Does the AT28C010E-12EM/883 support true page write functionality?
Yes, the AT28C010E-12EM/883 supports true hardware-accelerated page write: it internally latches up to 128 bytes with a single address setup, then executes the full write autonomously using an internal control timer. The 10 ms maximum page write cycle time applies regardless of whether 1 or 128 bytes are loaded, and all bytes must reside within the same page (defined by A7–A16), as confirmed in Section 5.9 of DS20006311A.
How does hardware write protection work on the AT28C010E-12EM/883?
Hardware write protection on the AT28C010E-12EM/883 combines four mechanisms: (1) VCC sense circuitry inhibits writes if supply drops below ~3.8 V; (2) a 5 ms internal power-on delay prevents writes until stable regulation is achieved; (3) write is blocked unless CE and WE are correctly asserted while OE is high; and (4) input noise filters reject sub-15 ns glitches on WE/CE pins-all documented in Section 5 of DS20006311A.
Can the AT28C010E-12EM/883 be used as a direct replacement for the AT28C010-12DM/883?
No-while the AT28C010E-12EM/883 and AT28C010-12DM/883 share identical electrical specifications and core functionality, they differ in package type (CLCC vs. CERDIP), pin layout, and thermal/mechanical behavior. The AT28C010E-12EM/883 uses a 32-lead CLCC with leads on all four sides, whereas the AT28C010-12DM/883 uses a 32-lead CERDIP with dual in-line pins. PCB layout and reflow profiles are not interchangeable.
What is the purpose of the 128-byte device identification area in the AT28C010E-12EM/883?
The 128-byte device identification area (addresses 1FF80H–1FFFFH) in the AT28C010E-12EM/883 is electrically isolated and programmed using A9 = 12 V ± 0.5 V. It is intended for permanent device-specific data such as calibration coefficients, serial numbers, or firmware version stamps-distinct from main array writes-and is retained independently per MIL-STD-883 qualification, as specified in Section 5 of DS20006311A.
