Product details
Overview
AT28C010E-15JU-T from Microchip Technology 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-15JU-T datasheet, AT28C010E-15JU-T pinout, AT28C010E-15JU-T application, or AT28C010E-15JU-T equivalent, key selection considerations include page-write timing (≤10 ms), DATA polling/Toggle Bit end-of-write detection, CMOS/TTL compatibility, 100,000-cycle endurance, and PLCC-32 packaging with green (Pb/Halide-free) compliance.
Technical Context
The AT28C010E-15JU-T implements a paged architecture with a 128-byte internal latch enabling simultaneous write of up to 128 bytes per internal programming cycle. Its dual-line control (CE/OE) allows flexible bus arbitration, while VCC sense and noise filtering prevent inadvertent writes during power transitions.
It features two end-of-write detection methods: DATA Polling on I/O7 (complement-to-data during write, true data after completion) and Toggle Bit on I/O6 (toggling until write finishes). The device includes 128 bytes of dedicated identification EEPROM accessible via A9 = 12V and supports optional software chip erase using a 6-byte command sequence.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Read Access Time | 150 ns max; enables direct replacement for SRAM in legacy 8-bit microcontroller systems |
| Page Write Cycle | 10 ms max; reduces firmware update latency vs. byte-write-only EEPROMs |
| Endurance | 100,000 write/erase cycles; validated for long-life field-programmable applications |
| Data Retention | 10 years at +85°C; ensures reliability in industrial control and automotive ECUs |

| Operating Temperature | –40°C to +85°C; qualified for industrial-grade embedded environments |
Pinout & Package
AT28C010E-15JU-T uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package with JEDEC-standard byte-wide pinout. Pin 1 is NC (No Connect). All I/O pins are CMOS/TTL compatible, and GND/VCC placement follows industry-standard decoupling layout practices.
| 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 | 8-bit parallel interface; I/O7 provides DATA Polling feedback; I/O6 provides Toggle Bit status |
| CE | Chip Enable | Active-low chip select; must be stable ≥50 ns before read/write to avoid data corruption |
| OE | Output Enable | Active-low output control; enables high-impedance state when deasserted to prevent bus contention |
| WE | Write Enable | Active-low write strobe; initiates byte or page write on falling edge; supports CE- or WE-controlled modes |
| VCC | Power Supply | +5V ±10% supply; internal VCC sense disables writes below ~3.8V to prevent partial programming |
| GND | Ground Reference | Signal and power ground; requires low-inductance connection for stable read/write margins |
| NC | No Connect | Pins 6 and 9 in TSOP variant; pin 1 in PLCC variant - must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| 128-byte Page Write | Reduces firmware update time by up to 128× vs. sequential byte writes; internal latching frees address/data bus during programming |
| DATA Polling & Toggle Bit | Hardware-verified end-of-write detection without timer overhead; eliminates need for fixed-delay polling loops in host firmware |
| Hardware Write Protection | VCC sense, 5 ms power-on delay, and noise filtering (<15 ns pulses rejected) prevent spurious writes during brown-out or EMI events |
| Software Data Protection (SDP) | User-configurable lock/unlock via 3-byte command sequence (AA/55/A0 enable; AA/55/80/AA/20/55 disable); persists across power cycles |
| 128-byte ID Memory | Dedicated EEPROM region (1FF80H–1FFFFH) accessible with A9 = 12V; enables unique device serialization and calibration storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the endurance rating of the AT28C010E-15JU-T?
The AT28C010E-15JU-T is rated for 100,000 write/erase cycles - explicitly denoted by the "E" suffix in the part number. This extended endurance is verified per JEDEC standards and supports applications requiring frequent field updates, such as industrial controller configuration storage. The base AT28C010-15JU variant offers only 10,000 cycles.
Does the AT28C010E-15JU-T support both byte and page write operations?
Yes, the AT28C010E-15JU-T supports both byte and page write modes. Page write allows up to 128 bytes to be loaded and programmed internally within a single 10 ms cycle, significantly accelerating firmware or parameter updates. Byte write remains available for single-location modifications without page boundary alignment.
How is end-of-write detection implemented on the AT28C010E-15JU-T?
The AT28C010E-15JU-T provides two independent hardware methods: DATA Polling on I/O7 (returns complement of written data until complete, then true data) and Toggle Bit on I/O6 (toggles between 0/1 until write finishes). Both methods eliminate reliance on fixed delays and improve host firmware determinism.
What package type does the AT28C010E-15JU-T use, and is it RoHS compliant?
The AT28C010E-15JU-T uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package, indicated by the "J" in the part number. It is green (Pb/Halide-free) and fully RoHS compliant per Microchip's DS20006331A datasheet, with matte tin (Sn) terminal finish and no restricted substances above threshold limits.
Can the AT28C010E-15JU-T be used as a direct replacement for older EPROMs like the 27C010?
The AT28C010E-15JU-T is not a pin-compatible drop-in replacement for the 27C010 EPROM due to differing control signal logic (e.g., OE/WE vs. OE/G*/PGM) and lack of UV-erasable functionality. However, its JEDEC-standard byte-wide pinout and 5V operation allow straightforward integration into existing 27C010 sockets with minor host firmware and timing adjustments.
