Description

AT29C010A-90JC is an Atmel (now Microchip) 1-Mbit, parallel, non-volatile EEPROM. It provides 128K × 8 organization (one byte wide data bus) with random, asynchronous access. The “90” indicates a typical 90 ns read access time. It operates from a single 5 V supply (common for this family) and uses standard control signals: Chip Enable (CE/CS), Output Enable (OE), and Write Enable (WE) to perform reads and writes to 8-bit I/O lines (I/O0–I/O7). Address inputs (A0–A16) select the byte to access. The JC suffix denotes a 32-pin JEDEC package (e.g., DIP/SOIC). Write cycles are non-destructive and require a defined tWC/tWR per the datasheet (typically a few ms). Applications include firmware or configuration storage for embedded systems, BIOS/firmware backup, and any non-volatile random-access memory needs. Note: this is a parallel EEPROM (not flash) and requires explicit write operations and cycle timing per the datasheet. For exact electrical characteristics, timings, and pinout, consult the AT29C010A-90JC datasheet.

Features

Key features of AT29C010A-90JC (parallell flash 1 Mbit):
- Memory: 1 Mbit (128K × 8) flash memory
- Speed grade: 90 ns access time
- Supply: 5V single-supply operation; TTL-compatible I/O
- Interface: 8-bit data bus; random access reads
- In-system programmable: supports standard program/erase operations
- Erase/Programming: chip and sector/block erase options
- Endurance/Data retention: typical ~100,000 write cycles; data retention on the order of years (datasheet specifies long-term retention)
- Protection: hardware protection features for sectors/blocks
- Power/ standby: low-power standby modes
- Packaging: -JC speed/package option (ceramic/leadframe style, 28-pin family packaging)
Note: exact block sizes, programming times, and electrical spec details are in the datasheet for the -90JC variant.
