Product details
Overview
AT29C010A-15JI from Atmel is a 1 Mbit (128K × 8) 5V-only Flash memory IC used for nonvolatile code and data storage in embedded systems, supporting in-system reprogramming via sector-based erase-and-program operations. It delivers 150 ns read access time, 10 ms sector program cycle time, and features hardware/software data protection, two 8K-byte boot blocks with independent lockout, and CMOS/TTL-compatible I/O.
For engineers reviewing the AT29C010A-15JI datasheet, AT29C010A-15JI pinout, AT29C010A-15JI application, or AT29C010A-15JI equivalent, this page provides verified technical context, real-world use cases, validated alternatives, and supply-ready procurement details specific to the industrial-grade PLCC-32 variant.
Technical Context
The AT29C010A-15JI operates as a parallel-interface Flash memory with 17 address lines (A0–A16), 8 bidirectional data lines (I/O0–I/O7), and standard control signals (CE, OE, WE). Its architecture supports byte-load programming, internal latching of 128-byte sectors, and automatic erase-before-program execution controlled by an on-chip timer.
It implements dual data protection: hardware-level VCC sensing (<3.8 V inhibits programming), noise filtering (<15 ns pulse rejection), and software-controlled lockout via 3-byte command sequences (AAh/55h/A0h for enable; AAh/55h/80h/AAh/55h/20h for disable). Boot block lockout is set independently for lower (0x0000–0x1FFF) and upper (0x1E000–0x1FFFF) 8K-byte regions using a 7-command algorithm.

Pinout & Package
AT29C010A-15JI uses a 32-lead Plastic J-Leaded Chip Carrier (PLCC-32) package, pin-compatible with industry-standard 32J footprint. The package is lead-free compliant and rated for industrial temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus; A0–A6 select byte within 128-byte sector, A7–A16 select sector address. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; supports DATA polling on I/O7 and TOGGLE BIT detection on I/O6 during programming. |
| CE | Chip Enable | Active-low chip select; must be low for read, program, or byte-load operations; high disables outputs and enters standby. |
| OE | Output Enable | Active-low output control; used with CE to gate data reads; high forces outputs to high-impedance state. |
| WE | Write Enable | Active-low write control; initiates byte loads and programs; combined with CE/OE determines operation mode. |
| VCC | Power Supply | +5 V ±10% main supply; powers core logic and I/O buffers; internally monitored for hardware write inhibition. |
| GND | Ground Reference | Signal and power ground reference; required for stable operation and noise immunity in mixed-signal boards. |
| NC | No Connect | Two unconnected pins (PLCC positions 6 and 13); must remain floating - no routing or termination required. |

FAQ
What is the maximum read access time specification for AT29C010A-15JI?
The AT29C010A-15JI has a maximum read access time of 150 ns, as confirmed by its ordering suffix "-15" and AC Read Characteristics table. This value applies across the full industrial temperature range (−40°C to +85°C) and ensures compatibility with 6–7 MHz system buses in legacy 8-bit and 16-bit controller designs. The 150 ns timing is guaranteed under VCC = 5 V ±10% and load conditions specified in the datasheet.
Does AT29C010A-15JI support both hardware and software data protection?
Yes, AT29C010A-15JI implements dual-layer protection: hardware protection includes VCC sensing (<3.8 V inhibits programming), 5 ms power-on delay, and noise filtering (<15 ns pulses rejected); software protection requires a three-byte command sequence (AAh/55h/A0h) to enable and the same sequence before each program cycle. Both mechanisms operate concurrently and are documented in the device's Operating Modes and Software Data Protection Enable Algorithm sections.
How many boot blocks does AT29C010A-15JI have, and can they be locked independently?
The AT29C010A-15JI has two 8K-byte boot blocks - one at the lowest addresses (0x0000–0x1FFF) and one at the highest (0x1E000–0x1FFFF). Each block supports independent programming lockout activation via a seven-command algorithm. Once enabled, the locked block cannot be erased or programmed, while other sectors remain fully reprogrammable - a feature critical for fail-safe bootloader architectures.
What package type is used for AT29C010A-15JI, and what are its key mechanical features?
AT29C010A-15JI uses a 32-lead Plastic J-Leaded Chip Carrier (PLCC-32, package code 32J) with JEDEC MS-016, Variation AE compliance. Key features include 1.27 mm pitch, 12.45 mm × 14.95 mm body dimensions, 3.35 mm max height, and lead coplanarity ≤0.102 mm. The package exposes no thermal pad and requires standard PLCC socket or reflow soldering with preheat and soak profiles per JEDEC J-STD-020.
Can AT29C010A-15JI be used in systems requiring more than 10,000 program/erase cycles?
The AT29C010A-15JI is rated for typical endurance of >10,000 program/erase cycles per sector, as stated in the Features section and validated across process lots. For applications demanding higher endurance, sector rotation algorithms should be implemented in firmware to distribute writes across multiple 128-byte sectors. No single sector is guaranteed beyond 10,000 cycles, but wear leveling extends effective lifetime significantly in well-designed systems.
