Product details
Overview
AT29BV010A-15JI from Atmel is a 1 Mbit (128K × 8) single-supply Flash memory IC operating at 2.7V–3.6V, featuring 150 ns read access time, 20 ms max sector program cycle, and dual 8K-byte boot blocks with independent programming lockout. It supports in-system reprogramming via software data protection and is used in embedded firmware storage for industrial microcontroller systems requiring reliable nonvolatile code retention.
For engineers reviewing the AT29BV010A-15JI datasheet, AT29BV010A-15JI pinout, AT29BV010A-15JI application, or AT29BV010A-15JI equivalent, key selection considerations include its PLCC-32 industrial-grade packaging, sector-based erase/program architecture, DATA polling and toggle-bit status detection, and boot-block lockout for secure bootloader storage.
Technical Context
The AT29BV010A-15JI implements a sector-erase Flash architecture with 1024 × 128-byte sectors and two dedicated 8K-byte boot blocks. Programming requires a three-byte software unlock sequence (AAh/55h/A0h) followed by byte-load cycles with ≤150 µs inter-byte timing, after which internal timers handle erase-and-program automatically.
It uses CMOS-compatible I/O with TTL-level input thresholds (VIL = 0.6 V, VIH = 2.0 V), supports both CE- and WE-controlled byte loading, and provides dual status verification methods: DATA polling on I/O7 and toggle-bit monitoring on I/O6 - enabling robust host-side program completion detection without external hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - sufficient for compact firmware images in resource-constrained MCUs. |
| Read Access Time | 150 ns max - enables direct execution from Flash (XIP) in systems with ≤6.7 MHz bus timing budgets. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with single-cell Li-ion or regulated 3.3 V rails, eliminating need for charge pumps or dual supplies. |
| Active Current | 15 mA at 5 MHz - low power consumption during firmware reads, supporting battery-backed or energy-sensitive applications. |
| Standby Current | 50 µA max (industrial temp) - ensures minimal quiescent draw when deselected, critical for always-on embedded controllers. |
| Endurance | >10,000 program/erase cycles per sector - supports field firmware updates over multi-year product lifecycles. |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments including factory automation and outdoor telemetry nodes. |
Pinout & Package
AT29BV010A-15JI is packaged in a 32-lead Plastic Leaded Chip Carrier (PLCC-32), compliant with JEDEC MS-016, Variation AE. Dimensions: 12.45 mm × 14.98 mm × 3.35 mm (max height), with J-leads and pin 1 identifier notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A0–A6 select byte within 128-byte sector, A7–A16 select sector. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface for read data output and program data input; supports DATA polling (I/O7) and toggle-bit (I/O6) status reporting. |
| CE | Chip Enable | Active-low chip select; must be low for read or program operations; high-Z output when high, preventing bus contention. |
| OE | Output Enable | Active-low output control; enables data output during read; must be high during program cycles to avoid conflict. |
| WE | Write Enable | Active-low write strobe; controls latching of address/data during byte load; used with CE for flexible timing control. |
| VCC | Power Supply | 2.7–3.6 V supply input; includes internal VCC sense circuitry that inhibits programming if voltage drops below ~2.0 V. |
| GND | Ground | Reference return path for all signals and power; decoupling capacitor required near VCC/GND pins for stable operation. |
| NC | No Connect | Two unconnected pins (PLCC pin 13 and pin 31); must remain floating - no external connection or pull-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h/2AAAh/5555h) required before each sector program - prevents accidental writes during noise events or power transients. |
| Dual Boot Block Lockout | Independent 8K-byte lower- and upper-address boot blocks; once locked, their contents are permanently protected from erase or program - secures bootloader integrity. |
| Sector-Based Reprogramming | 1024 × 128-byte sectors with internal address/data latches - allows host CPU to release bus after loading 128 bytes, improving system concurrency. |
| Status Detection Methods | Simultaneous support for DATA polling (I/O7 complement-to-data) and toggle-bit (I/O6 toggling) - gives host flexibility in interrupt-driven or polling-based firmware update logic. |
| Hardware Write Inhibit | VCC sense, 10 ms power-on delay, OE/CE/WE control gating, and 15 ns noise filtering - provides layered protection against spurious programming. |

| MX29LV160CBTI-70G | 16 Mbit density, 70 ns access, 2.7–3.6 V, boot-block architecture with top/bottom configuration, TSOP-48 | Higher density and different pinout; boot block layout differs (16K/48K vs. dual 8K), requiring PCB redesign | Choose for future-proofing with larger firmware footprints, but expect layout changes and validation effort due to pin count and sector mapping differences. |
Compared with SST39VF010-70-4C-NHE and MX29LV160CBTI-70G, the AT29BV010A-15JI delivers unique value in industrial-grade reliability, dual independent boot block lockout, and PLCC-32 mechanical robustness - making it optimal for legacy MCU platforms needing secure, long-lifecycle firmware storage without board redesign.

FAQ
What is the maximum read access time specified for the AT29BV010A-15JI?
The AT29BV010A-15JI has a maximum read access time of 150 ns, measured from address valid or CE/OE assertion to valid data on I/O0–I/O7. This parameter is guaranteed across the full industrial temperature range (−40°C to +85°C) and 2.7–3.6 V supply, enabling deterministic timing in 8-bit and 16-bit microcontroller interfaces without wait-state insertion.
Does the AT29BV010A-15JI support hardware reset or power-on initialization sequences?
The AT29BV010A-15JI does not include an internal hardware reset circuit. However, it incorporates VCC sense and a 10 ms power-on delay that automatically inhibits programming until VCC stabilizes above ~2.0 V. System designers must ensure ≥20 ms delay after VCC reaches specification before initiating any operation, as stated in the datasheet's Note 1.
How is boot block lockout enabled or verified on the AT29BV010A-15JI?
Boot block lockout on the AT29BV010A-15JI is enabled via a seven-command software algorithm targeting addresses 00000h (lower block) or 1FFFFh (upper block). Verification is performed in Software Product Identification mode: reading address 00002h returns FEh if unlocked or FFh if locked for the lower block; 1FFF2h serves the same purpose for the upper block.
Can the AT29BV010A-15JI be programmed using standard EPROM programmers?
No - the AT29BV010A-15JI requires in-system programming via its parallel interface and specific software command sequences (e.g., unlock codes AAh/55h/A0h). It is not compatible with conventional EPROM UV-erasable or parallel-programmer voltage-signature protocols. Programming must occur with VCC applied and follow the byte-load timing constraints (≤150 µs inter-byte window).
What happens if the software data protection sequence is interrupted during programming of the AT29BV010A-15JI?
If the three-byte unlock sequence (5555h/2AAAh/5555h) is incomplete or corrupted, the AT29BV010A-15JI remains in protected state and ignores subsequent write attempts. No data is altered, and the device continues normal read operation. The internal write timer (tWC) may activate briefly, but no sector erase or program occurs - ensuring zero risk of unintended memory corruption.
