Product details
Overview
AT28C010E-15JI from Atmel is a 1-Mbit (128K × 8) paged parallel EEPROM with JEDEC-standard byte-wide pinout, 150 ns read access time, 10 ms maximum page write cycle, and industrial temperature range (–40°C to +85°C). It operates from a single 5V ±10% supply, supports hardware/software data protection, and is used in firmware storage, configuration memory, and boot code retention for embedded controllers.
For engineers reviewing the AT28C010E-15JI datasheet, AT28C010E-15JI pinout, AT28C010E-15JI application, or AT28C010E-15JI equivalent, key selection considerations include its 100K-cycle endurance, DATA polling and toggle-bit write completion detection, CMOS/TTL-compatible I/O, and PLCC-32 industrial-grade packaging.
Technical Context
The AT28C010E-15JI implements a paged architecture with a 128-byte internal page register, enabling simultaneous write of 1–128 bytes per cycle. Its internal control timer automates programming after address/data latching, freeing the bus during writes.
It features dual write detection methods-DATA polling on I/O7 and toggle-bit behavior on I/O6-and includes VCC sense, power-on delay, noise filtering, and software data protection (SDP) to prevent inadvertent writes. Device identification space (128 bytes at 1FF80H–1FFFFH) and optional 6-byte chip erase are supported.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - supports full byte-addressable nonvolatile storage without external logic. |
| Read Access Time | 150 ns max - enables direct replacement of SRAM in legacy 8-bit microcontroller systems with no wait-state insertion. |
| Page Write Cycle | 10 ms max - reduces firmware update latency vs. byte-write-only EEPROMs; supports burst programming of up to 128 bytes. |
| Endurance | 100,000 write/erase cycles - validated high-endurance variant ('E' suffix), suitable for field-upgradable configuration tables. |
| Data Retention | 10 years at +85°C - ensures long-term reliability in industrial control and telecom infrastructure applications. |
| Supply Voltage | 5V ±10% - compatible with standard TTL/CMOS logic rails; no auxiliary voltage required for programming or read. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor drives, PLCs, and base station equipment. |
| Standby Current | 200 µA CMOS - enables low-power operation in battery-backed or energy-constrained systems. |
Pinout & Package
AT28C010E-15JI is supplied in a 32-lead Plastic J-Leaded Chip Carrier (PLCC-32) package with JEDEC MS-016AE outline, lead pitch 0.050", body size 1.15" × 1.15", and pin 1 marked by index notch. Pin 1 is designated "Don't Connect" (DC) per datasheet.
| 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. |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS/TTL-compatible 8-bit data path; I/O7 used for DATA polling, I/O6 for toggle-bit write status indication. |
| CE | Chip Enable | Active-low chip select; must be low with OE low and WE high for read; inhibits writes when high. |
| OE | Output Enable | Active-low output control; places I/O pins in high-impedance state when high, preventing bus contention. |
| WE | Write Enable | Active-low write strobe; initiates byte or page write on falling edge; combined with CE for robust write control. |
| VCC | Power Supply | +5V ±10% main supply; powers core logic and memory array; internal VCC sense prevents writes below ~3.8V. |
| GND | Ground Reference | Signal and power ground reference for all inputs, outputs, and internal circuitry. |
| NC / DC | No Connect / Don't Connect | Pin 1 (PLCC) is DC - must remain unconnected; other NC pins are internally unused and must be left floating. |
Key Features
| Feature | Design Value |
|---|---|
| 128-byte Page Register | Enables burst programming without host CPU bus occupation during internal write timing - improves system throughput in firmware update routines. |
| Hardware Write Protection | VCC sense, 5 ms power-on delay, and noise filtering (<15 ns pulse rejection) eliminate false writes during power ramp-up or EMI events. |
| Software Data Protection (SDP) | User-configurable 3-byte command sequence (AAh/55h/A0h) enables/disables write lock - supports secure field updates without hardware modification. |
| DATA Polling & Toggle Bit | Real-time, bus-compatible write completion signaling via I/O7 complement or I/O6 toggling - eliminates need for fixed delays or external timers. |
| Device Identification Area | 128-byte dedicated EEPROM space (1FF80H–1FFFFH) accessible with A9 = 12V - supports unique device serialization and calibration data storage. |
| JEDEC Byte-Wide Pinout | Pin-compatible with industry-standard EPROMs and SRAMs - allows drop-in replacement in existing 8-bit memory interfaces without PCB redesign. |
Applications
| Industrial PLC Configuration Storage | Legacy Microcontroller Boot Memory |

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15JI | 10K-cycle endurance (vs. 100K); same pinout, timing, and feature set except endurance and SDP default state. | Suitable for low-update-frequency applications like static configuration storage where write cycles <1K expected over lifetime. | Select only if cost sensitivity outweighs field-upgrade longevity; verify write-cycle budget against application requirements. |
| MX28F1000PC-15 | Intel-compatible 1-Mbit Flash (not EEPROM); requires sector erase before write; no page register or DATA polling. | Requires full 64KB sector erase for any update; incompatible with byte/page write protocols and real-time polling. | Not a functional substitute - use only if migrating to Flash architecture with full firmware rewrite capability and erase management. |
Compared with AT28C010E-15JI, the AT28C010-15JI offers identical interface and timing but lower endurance, while MX28F1000PC-15 requires architectural changes to support erase-before-write and lacks native page-write efficiency - making AT28C010E-15JI optimal for reliable, low-overhead in-field updates.

FAQ
What is the endurance rating of the AT28C010E-15JI?
The AT28C010E-15JI is rated for 100,000 write/erase cycles - confirmed by Atmel's 'E' suffix designation indicating high-endurance variant. This exceeds standard AT28C010 (10K cycles) and supports frequent firmware or configuration updates in industrial field-deployed equipment. The endurance applies across the full industrial temperature range (–40°C to +85°C) and is validated per JEDEC standards. AT28C010E-15JI maintains this rating without derating under typical 5V ±10% supply conditions.
Does the AT28C010E-15JI require a 12V programming voltage?
No, the AT28C010E-15JI operates from a single 5V ±10% supply for both read and write operations. A 12V ±0.5V voltage is required only for accessing the optional 128-byte device identification area (addresses 1FF80H–1FFFFH) - standard memory array reads and writes function entirely at 5V. The AT28C010E-15JI integrates internal charge pumps and VCC sensing, eliminating external high-voltage generators for normal operation.
How does write completion detection work on the AT28C010E-15JI?
The AT28C010E-15JI provides two hardware-supported methods: DATA polling on I/O7 (returns complement of last written byte until complete) and toggle-bit detection on I/O6 (toggles between 0/1 during write, then stabilizes). Both operate without halting the host bus and are valid at any point during the 10 ms internal write cycle. These mechanisms replace fixed-delay loops and ensure deterministic timing for AT28C010E-15JI integration in real-time systems.
Is the AT28C010E-15JI pin-compatible with standard SRAMs?
Yes, the AT28C010E-15JI uses JEDEC-approved byte-wide pinout matching common 128K×8 SRAMs (e.g., IS61LV12816) and EPROMs (e.g., 27C1001), including identical A0–A16, I/O0–I/O7, CE, OE, and WE placement. Its PLCC-32 package (32J) allows direct socket replacement in existing designs. However, write timing and protection logic differ - AT28C010E-15JI requires proper WE/CE sequencing and supports page writes, unlike SRAM.
What is the purpose of the Software Data Protection (SDP) feature on the AT28C010E-15JI?
The SDP feature on AT28C010E-15JI prevents accidental writes using a 3-byte unlock sequence (AAh → 55h → A0h to address 5555h/2AAAh/5555h). Once enabled, all subsequent writes require repeating this sequence - protecting calibration data or firmware from corruption during power transitions or software faults. AT28C010E-15JI ships with SDP disabled; the feature is fully user-controllable and persists through power cycles.
