Product details
Overview
AT28C010E-15JU-235 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-235 datasheet, AT28C010E-15JU-235 pinout, AT28C010E-15JU-235 application, or AT28C010E-15JU-235 equivalent, key selection criteria include page-write timing (≤10 ms), DATA Polling/Toggle Bit end-of-write detection, 100,000-cycle endurance, CMOS/TTL compatibility, and PLCC-32 packaging with green (Pb/Halide-free) compliance.
Technical Context
The AT28C010E-15JU-235 implements a paged architecture with a 128-byte internal latch, enabling simultaneous write of 1–128 bytes within a single page defined by A7–A16. Its dual-line control (CE/OE) enables bus contention avoidance during read operations, while WE-controlled or CE-controlled write modes support flexible system integration.
It features VCC-sense write inhibition below 3.8 V, 5 ms power-on delay before write enable, noise filtering on WE/CE inputs (<15 ns rejection), and optional software data protection using a three-byte command sequence. Device identification space (128 bytes at 1FF80H–1FFFFH) is accessible via 12 V on A9.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8 bits); supports full firmware image or multi-parameter configuration storage without external expansion. |
| Read Access Time | 150 ns max; compatible with 5 MHz bus timing and legacy microcontroller interfaces requiring fast random-access reads. |
| Page Write Cycle | 10 ms max; enables efficient bulk updates (e.g., logging, calibration tables) with minimal CPU wait time. |
| Endurance | 100,000 write/erase cycles; validated for long-term field deployment in industrial control and telecom equipment. |
| Data Retention | 10 years at +85°C; ensures reliable nonvolatile storage across product lifecycle without refresh. |
| Supply Voltage | 5 V ±10%; eliminates need for dedicated voltage regulators in 5 V systems and simplifies power design. |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including factory automation and outdoor infrastructure. |
| Standby Current | 200 µA (CMOS); reduces quiescent power in battery-backed or low-power sleep modes. |
Pinout & Package
AT28C010E-15JU-235 uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package with JEDEC-standard byte-wide pinout. Pin 1 is No Connect (NC). The device is Pb/Halide-free and RoHS-compliant.
| 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 writes. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface compatible with standard microcontroller data buses; supports true read/write without direction control pins. |
| CE | Chip Enable | Active-low chip select; deassertion places outputs in high-impedance state to prevent bus contention. |
| OE | Output Enable | Active-low output gate; allows read access independent of CE, enabling multiplexed bus sharing. |
| WE | Write Enable | Active-low write strobe; initiates byte or page write when CE is low and OE is high. |
| VCC | Power Supply | +5 V ±10% supply input; includes internal VCC-sense circuitry to inhibit writes during brown-out conditions. |
| GND | Ground Reference | Signal and power ground reference; decoupling required per JEDEC layout guidelines for stable operation. |
| NC (Pin 1, Pin 30) | No Connect | Unbonded pins; must remain unconnected per datasheet to avoid functional interference. |
Key Features
| Feature | Design Value |
|---|---|
| 128-byte Page Write | Reduces firmware update time by up to 128× vs. byte-write; eliminates CPU polling overhead during multi-byte writes. |
| DATA Polling (I/O7) | Enables real-time write completion detection without timers or interrupts; supports deterministic system response. |
| Toggle Bit (I/O6) | Provides alternative asynchronous write status monitoring; usable when I/O7 is reserved for data integrity checks. |
| Software Data Protection | Three-byte command sequence prevents accidental writes during power transitions or firmware bugs; user-configurable enable/disable. |
| Hardware Write Inhibit | VCC-sense, 5 ms power-on delay, and noise filtering eliminate false writes caused by supply instability or EMI. |
| Device Identification Area | 128-byte dedicated EEPROM region (1FF80H–1FFFFH) accessible at 12 V on A9 for unique serialization or calibration data. |

FAQ
What is the maximum page write size supported by the AT28C010E-15JU-235?
The AT28C010E-15JU-235 supports a fixed 128-byte page write operation. All bytes written in a single page cycle must reside within the same 128-byte boundary defined by address bits A7–A16. Attempting to cross page boundaries during a page write will terminate the operation and initiate internal programming.
Does the AT28C010E-15JU-235 require external high-voltage circuitry for programming?
No, the AT28C010E-15JU-235 performs all write and erase operations using only its standard 5 V supply. High voltage (12 V) is required exclusively for accessing the 128-byte device identification area at addresses 1FF80H–1FFFFH-not for normal program/erase functions.
How does DATA Polling work on the AT28C010E-15JU-235 during a write cycle?
During a write cycle, reading the last written byte returns the complement of that data on I/O7. Once the internal programming completes, true data appears on I/O7 and all other I/O lines. This allows the host processor to poll I/O7 without timers or interrupts to detect write completion.
Is the AT28C010E-15JU-235 pin-compatible with older Atmel AT28C010 variants?
Yes, the AT28C010E-15JU-235 maintains full JEDEC-standard byte-wide pinout compatibility with all AT28C010 family members, including AT28C010-12JU and AT28C010-15JU. Differences are limited to endurance rating (100K vs. 10K) and marking-no PCB or firmware changes are needed for drop-in replacement.
What is the purpose of the NC pins on the AT28C010E-15JU-235 PLCC package?
The AT28C010E-15JU-235 has two NC pins: Pin 1 and Pin 30. These are unconnected internally and must remain floating-no pull-up, pull-down, or routing is permitted. Connecting them may cause undefined behavior or damage per the official Microchip datasheet DS20006331A.
