Product details
Overview
AT28C010E-12TU from Microchip Technology is a 1-Mbit (128K × 8) paged parallel EEPROM with 120 ns read access time, internal 128-byte page latch, and single 5V ±10% supply. It supports hardware/software data protection, DATA polling, and toggle-bit write completion detection for embedded firmware storage in industrial control systems.
For engineers reviewing the AT28C010E-12TU datasheet, AT28C010E-12TU pinout, AT28C010E-12TU application, or AT28C010E-12TU equivalent, this page delivers verified electrical specs, JEDEC-compliant byte-wide pin mapping, endurance and retention metrics, industrial temperature operation (–40°C to +85°C), and green Pb/halide-free packaging details.
Technical Context
The AT28C010E-12TU implements a CMOS-based nonvolatile memory architecture with integrated address/data latching for 1–128-byte page writes and automatic internal timing control. Its dual-line enable logic (CE/OE) enables bus contention avoidance in SRAM-compatible interfaces.
It features VCC-sense write inhibition below 3.8 V, 5 ms power-on delay before write enable, and noise filtering rejecting <15 ns pulses on WE/CE. The device includes 128 bytes of dedicated identification EEPROM accessible via A9 = 12 V and supports optional software chip erase via 6-byte command sequence.

Pinout & Package
AT28C010E-12TU is offered in two JEDEC-standard 32-lead packages: PLCC (J-lead) and TSOP (Type I, 8 × 20 mm). Both share identical pin functions and byte-wide JEDEC-compliant pinout. Pin 1 is marked on PLCC via corner chamfer; TSOP uses notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus; A7–A16 define 128-byte page boundary for page write operations |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; I/O7 used for DATA polling, I/O6 for toggle-bit status monitoring |
| CE | Chip Enable | Active-low primary selection signal; must be stable ≥50 ns before read access |
| OE | Output Enable | Active-low output control; enables high-impedance state when deasserted to prevent bus contention |
| WE | Write Enable | Active-low write strobe; falling edge latches data; supports both CE- and WE-controlled write modes |
| VCC | Power Supply | +5 V ±10% supply; powers core and I/O; internal VCC sense disables writes if voltage drops below 3.8 V |
| GND | Ground Reference | Signal and power return; decoupling capacitor required within 10 mm of VCC/GND pins |
| NC | No Connect | Pins 6 & 9 (TSOP), Pin 1 (PLCC); must remain unconnected per datasheet |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-12TU | 10,000-cycle endurance; same speed/package; no 'E' suffix | Suitable for infrequently updated configurations where cost sensitivity outweighs longevity | Select when firmware update frequency is ≤100× over product lifetime |
| MN63F1002BGP | 1 Mbit, 150 ns access, 3.3 V only, SOIC-32; no page write or DATA polling | Requires level-shifting for 5 V systems; lacks real-time write status feedback | Choose only for new 3.3 V designs prioritizing footprint over legacy compatibility |
Compared with AT28C010-12TU, the AT28C010E-12TU delivers 10× higher endurance for field-upgradable systems, while MN63F1002BGP trades write flexibility and voltage compatibility for lower static power in modern 3.3 V architectures.

FAQ
What is the maximum page write size supported by the AT28C010E-12TU?
The AT28C010E-12TU supports a fixed 128-byte page write operation. All bytes written within a single page write cycle must reside on the same 128-byte boundary defined by address bits A7–A16. The device internally latches up to 128 bytes before initiating the 10 ms internal programming sequence. This capability is confirmed in Section 5.8 and Table 5-4 of the DS20006331A datasheet and applies specifically to the AT28C010E-12TU.
Does the AT28C010E-12TU require external high-voltage circuitry for programming?
No, the AT28C010E-12TU operates from a single 5 V ±10% supply and requires no external high-voltage programming circuitry. All write and erase operations-including page writes, byte writes, and optional chip erase-are executed using standard 5 V logic levels. The 12 V requirement mentioned in the datasheet applies exclusively to the optional device identification area (1FF80H–1FFFFH), not to main array programming. The AT28C010E-12TU itself functions fully at 5 V.
How does software data protection work on the AT28C010E-12TU?
Software data protection on the AT28C010E-12TU is enabled via a three-byte unlock sequence written to specific addresses (5555H, 2AAAH, then 5555H). Once activated, all subsequent writes to the main memory array require repeating this sequence before data. The AT28C010E-12TU retains protection state across power cycles. Disabling requires a separate five-byte sequence. These algorithms are detailed in Sections 5.11 and 5.12 of the official datasheet and are fully implemented in the AT28C010E-12TU.
Is the AT28C010E-12TU pin-compatible with the standard AT28C010-12TU?
Yes, the AT28C010E-12TU is fully pin-compatible and functionally identical to the AT28C010-12TU in all respects except write endurance: the 'E' suffix denotes 100,000-cycle endurance versus 10,000 cycles for the base part. Both share identical pinout, timing specifications, package options (PLCC/TSOP), and electrical characteristics. No PCB layout changes are required when upgrading from AT28C010-12TU to AT28C010E-12TU.
What package options are available for the AT28C010E-12TU?
The AT28C010E-12TU is available in two RoHS-compliant, green (Pb/halide-free) packages: 32-lead PLCC (plastic leaded chip carrier) and 32-lead TSOP (thin small outline package, Type I, 8 × 20 mm). Both packages implement the JEDEC-approved byte-wide pinout and are interchangeable at the board level. The 'U' suffix in AT28C010E-12TU explicitly denotes industrial temperature grade and matte tin terminal finish for both variants.
