Description
Overview of AT29C010A-90JC
- Type: 1-Mbit, parallel (8‑bit) flash memory from Atmel (now Microchip).
- Organization: 128 K × 8 data array; random access with an 8‑bit data bus.
- Interface/Package: Parallel memory interface; commonly in a 28-pin package (suffix JC indicates package style).
- Speed: 90 ns access time (fast read performance for code storage).
- Power/voltage: Typically 5 V supply for read/write; programming typically requires a higher Vpp (around 12 V) with a standard command sequence.
- Operation: Nonvolatile storage with erase/program capability; uses chip/byte programming via control signals (CE, OE, WE) and address lines.
- Features: In-system/inline programming support; device erase and programming via standard flash/EPROM-like command set; suitable for code storage and boot ROM in microcontroller-based systems.
- Applications: BIOS/firmware storage, embedded system code memory, and other applications needing reliable, nonvolatile parallel flash.
Note: Always reference the latest datasheet for exact pinout, voltages, and programming requirements.
