Product details
Overview
AT28C010E-12PC from Atmel is a 1-Mbit (128K × 8) paged parallel EEPROM with JEDEC-standard byte-wide pinout, 120 ns read access time, 10 ms maximum page write cycle, and high-endurance 10⁵ write cycles. It operates from a single 5V ±10% supply and supports both commercial (0°C to 70°C) and industrial (−40°C to 85°C) temperature ranges in 32-lead PDIP packaging.
For engineers reviewing the AT28C010E-12PC datasheet, AT28C010E-12PC pinout, AT28C010E-12PC application, or AT28C010E-12PC equivalent, this device serves as a drop-in replacement for legacy SRAM-based boot memory and firmware storage where nonvolatility, hardware/software data protection, and page-write efficiency are required in embedded control, industrial PLCs, and telecom line cards.
Technical Context
The AT28C010E-12PC implements a CMOS-based parallel EEPROM architecture with an internal 128-byte 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 flexible 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 write cycle. Hardware write inhibition includes VCC sense (<3.8 V), 5 ms power-on delay, noise filtering (<15 ns pulses rejected), and CE/OE/WE state locking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - directly replaces 128K × 8 SRAM in boot code storage without external battery or backup. |
| Read Access Time | 120 ns max - enables direct interface with 8-MHz Z80, 68K, or 8051 microcontrollers without wait states. |
| Page Write Cycle | 10 ms max for 1–128 bytes - reduces firmware update latency by >90% vs. byte-by-byte programming. |
| Endurance | 100,000 write/erase cycles - supports field firmware upgrades over 10+ years in industrial controllers. |
| Supply Voltage | 5V ±10% - compatible with legacy 5V logic families and eliminates need for voltage translation. |
| Standby Current | 200 µA CMOS - enables low-power operation in battery-backed or energy-constrained systems. |
| Data Retention | 10 years at 85°C - ensures firmware integrity across full industrial temperature lifecycle. |
Pinout & Package
AT28C010E-12PC is supplied in a 32-lead, 0.600" wide plastic dual inline package (PDIP), JEDEC MS-011 compliant, with through-hole mounting and standard 0.1" lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A7–A16 define page boundaries for 128-byte page writes. |
| CE | Chip Enable | Active-low global enable; when high, places outputs in high-impedance and inhibits all writes - used for device selection in multi-chip memory maps. |
| OE | Output Enable | Active-low read control; allows shared data bus usage with other peripherals without requiring external tri-state logic. |
| WE | Write Enable | Active-low write strobe; falling edge latches address and data; combined with CE, initiates byte or page write sequences. |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS/TTL-compatible 8-bit data path; supports true read-modify-write and DATA POLLING on I/O7/I/O6 during write cycles. |
| GND / VCC | Power Terminals | Single 5V supply with dedicated ground; decoupling capacitor placement near VCC/GND pins is mandatory for stable page-write timing. |
| NC | No Connect | Pins 1, 32 (PDIP) - must remain unconnected per datasheet; routing traces to these pins violates JEDEC pinout compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Page Write | Internal 128-byte latch and timer eliminate host CPU overhead - enables background writes while processor executes other tasks. |
| DATA POLLING & TOGGLE BIT | Dual asynchronous write-complete detection methods allow polling from any address without halting system clocks or requiring dedicated status registers. |
| Hardware + Software Data Protection | VCC sensing, 5 ms power-up delay, and 3-byte SDP command sequence prevent corruption during brown-out, reset, or hot-plug events. |
| JEDEC Byte-wide Pinout | Direct pin-for-pin compatibility with industry-standard EPROMs and SRAMs - no PCB redesign needed for migration from 27C512 or 62256. |
| Industrial Temperature Range | −40°C to +85°C operation validated per MIL-STD-883 - suitable for under-hood automotive ECUs and outdoor telecom base stations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-12PC | Standard endurance: 10K cycles; same pinout, timing, and voltage specs. | Limited to ≤1K field firmware updates over product lifetime. | Select when cost sensitivity outweighs long-term field upgrade needs. |
| MX28F1000PC-12 | Intel-compatible 1-Mbit flash; requires sector erase before write; no page-write mode. | Requires full 128K erase before reprogramming - unsuitable for partial configuration updates. | Choose only if migrating from Intel 28F-series and accepting erase-before-write latency. |
Compared with AT28C010-12PC and MX28F1000PC-12, the AT28C010E-12PC uniquely delivers 10× higher endurance and true page-write concurrency - making it the only option among the three that supports frequent, low-latency, partial-memory updates in mission-critical embedded systems.

FAQ
What is the endurance rating of the AT28C010E-12PC?
The AT28C010E-12PC is rated for 100,000 write/erase cycles - ten times higher than the standard AT28C010-12PC. This high-endurance specification is achieved through enhanced oxide quality and optimized programming algorithms in Atmel's CMOS process, enabling repeated field firmware updates in industrial control applications without premature wear-out. The AT28C010E-12PC maintains full compatibility with all timing, voltage, and pinout specifications of the base part.
Does the AT28C010E-12PC support page write operations, and what is the maximum page size?
Yes, the AT28C010E-12PC supports page write operations with a fixed page size of 128 bytes. During a page write, up to 128 consecutive bytes within the same page (defined by A7–A16) can be loaded sequentially within 150 µs intervals, after which the internal timer automatically executes the full write cycle in ≤10 ms. This capability is identical across all AT28C010 variants, including the AT28C010E-12PC, and eliminates the need for external write sequencing logic.
How does hardware data protection work on the AT28C010E-12PC?
The AT28C010E-12PC implements four hardware data protection mechanisms: (1) VCC sense circuitry disables writes if supply drops below ~3.8 V; (2) a 5 ms internal power-on delay prevents writes during voltage ramp-up; (3) write inhibition occurs if CE is high, OE is low, or WE is high; and (4) input noise filters reject pulses <15 ns on CE/WE. These features operate independently of software and are active on every AT28C010E-12PC power cycle - ensuring robustness even in electrically noisy industrial environments.
Can the AT28C010E-12PC be used as a direct replacement for the AT28C010-12PC?
Yes, the AT28C010E-12PC is a pin-, package-, and timing-compatible drop-in replacement for the AT28C010-12PC, sharing identical DC/AC specifications, JEDEC pinout, and functional behavior. The only difference is the enhanced 100K-cycle endurance; all read/write timing, voltage thresholds, and protection features remain unchanged. No PCB or firmware modifications are required when upgrading from AT28C010-12PC to AT28C010E-12PC.
What package type is used for the AT28C010E-12PC?
The AT28C010E-12PC uses a 32-lead, 0.600" wide plastic dual inline package (PDIP), designated as package code "32P6" in Atmel's ordering nomenclature. This through-hole package features standard 0.1" lead spacing, JEDEC MS-011 outline compliance, and is rated for both commercial (0°C to 70°C) and industrial (−40°C to 85°C) temperature operation - matching the full specification of the AT28C010E-12PC datasheet.
