Product details
Overview
AT28C010-15TU from Microchip Technology is a 1-Mbit (128K × 8) paged parallel EEPROM designed for nonvolatile data storage in embedded control, firmware boot code retention, and configuration memory applications. It delivers 150 ns read access time, supports 1–128-byte page writes with ≤10 ms internal write cycle time, operates from a single 5V ±10% supply, and features hardware/software data protection for industrial-grade reliability.
For engineers reviewing the AT28C010-15TU datasheet, AT28C010-15TU pinout, AT28C010-15TU application, or AT28C010-15TU equivalent, key selection criteria include JEDEC-compliant byte-wide parallel interface timing, CMOS/TTL compatibility, DATA Polling and Toggle Bit write completion detection, and industrial temperature operation (–40°C to +85°C).
Technical Context
The AT28C010-15TU implements a paged architecture with a 128-byte internal latch enabling burst writes without external address/data bus hold. Its dual-line chip enable (CE) and output enable (OE) control allows flexible bus arbitration, while write operations are governed by internal timing logic-no external programming voltage or pulse sequencing required beyond standard WE/CE transitions.
It integrates VCC sense (write inhibit below 3.8 V), 5 ms power-on delay, noise filtering on WE/CE inputs, and optional software data protection (SDP) via three-byte command sequences. The device includes 128 bytes of dedicated identification EEPROM accessible at 1FF80H–1FFFFH using A9 = 12 V.

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 | 120 ns read access time; otherwise identical architecture, pinout, and feature set | Suitable where tighter read timing is required (e.g., >6 MHz bus systems) | Select when system timing budget demands sub-150 ns access; same PCB layout and firmware |
| MN63C010-15PL | Same density and speed, but uses 32-pin PDIP package; lacks software data protection and device ID area | Preferred for through-hole prototyping or legacy board refresh where PLCC socketing is unavailable | Choose only if PLCC/TSOP footprint is incompatible; verify absence of SDP does not compromise system robustness |
Compared with AT28C010-15TU, the AT28C010-12TU offers faster read performance with zero design change, while the MN63C010-15PL trades advanced protection features for through-hole compatibility-making AT28C010-15TU optimal for new industrial designs demanding security and surface-mount integration.

FAQ
What is the maximum page write size supported by the AT28C010-15TU?
The AT28C010-15TU supports up to 128 bytes per page write operation, enabled by its internal 128-byte data latch. Each byte must be loaded within 150 µs of the prior byte (tBLC), and all addresses must reside on the same page defined by A7–A16. This capability is confirmed in Section 5.8 of the DS20006331A datasheet and applies directly to the AT28C010-15TU variant.
Does the AT28C010-15TU require an external programming voltage for write operations?
No, the AT28C010-15TU performs all write operations-including byte, page, and chip erase-using only the standard 5 V ±10% VCC supply. No external VPP or high-voltage programming signal is needed. This is explicitly stated in the "Features" section and verified in AC Write Characteristics (Table 5-3) and Software Chip Erase documentation for the AT28C010-15TU.
How is write completion detected on the AT28C010-15TU?
The AT28C010-15TU provides two hardware methods: DATA Polling (monitoring complement state on I/O7) and Toggle Bit (observing toggling on I/O6). Both are active during write cycles and cease when programming completes. These mechanisms are fully documented in Sections 5.14–5.17 and apply identically to the AT28C010-15TU speed grade.
Is the AT28C010-15TU pin-compatible with other members of the AT28C010 family?
Yes, all AT28C010 variants-including AT28C010-12TU, AT28C010-15TU, and AT28C010-12JC-share identical 32-pin JEDEC byte-wide pinouts across PLCC and TSOP packages. Pin functions, electrical behavior, and timing parameters (except access time) are consistent, enabling drop-in replacement between speed grades like AT28C010-15TU and AT28C010-12TU.
What packaging options are offered for the AT28C010-15TU?
The AT28C010-15TU is supplied exclusively in green (Pb/Halide-free) 32-lead PLCC and 32-lead TSOP (8 × 20 mm) packages. The "U" suffix denotes industrial temperature range (–40°C to +85°C) and matte tin terminal finish. No PDIP or SOIC variants exist for this speed grade, as confirmed in Packaging Information (Section 6) of the AT28C010-15TU datasheet.
