Product details
Overview
AT29BV010A-12TI from Atmel is a 1 Mbit (128K × 8) single-supply Flash memory IC designed for in-system reprogrammability in embedded control and boot code storage applications. It operates from 2.7V to 3.6V, delivers 120 ns read access time, supports sector-based programming with 1024 × 128-byte sectors, and features two 8K-byte boot blocks with independent lockout capability.
For engineers reviewing the AT29BV010A-12TI datasheet, AT29BV010A-12TI pinout, AT29BV010A-12TI application, or AT29BV010A-12TI equivalent, key selection considerations include its industrial temperature range (–40°C to +85°C), software data protection sequence, DATA polling/Toggle Bit program status detection, and PLCC-32 or TSOP-32 package compatibility.
Technical Context
The AT29BV010A-12TI implements a sector-erase-and-program architecture with internal address/data latches for 128-byte loads, eliminating external buffering requirements during reprogramming. Its dual boot blocks (first/last 8K bytes) support secure firmware startup in systems booting from either low or high addresses.
Hardware protection includes VCC sense (<2.0V inhibit), 10 ms power-on delay, and noise filtering on WE/CE inputs; software protection requires a three-byte command sequence (AAh→55h→A0h) before any sector write. Program completion is verified via I/O7 DATA polling or I/O6 Toggle Bit behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - supports full firmware image storage for 8-bit microcontrollers. |
| Read Access Time | 120 ns max - enables direct execution from flash (XIP) in timing-critical 5 MHz bus systems. |
| Supply Voltage | 2.7V to 3.6V single supply - eliminates need for charge pumps or auxiliary voltage rails in battery-powered designs. |
| Active Current | 15 mA at 5 MHz - defines dynamic power budget for continuous read operations in portable equipment. |
| Standby Current | 40 µA CMOS standby - ensures ultra-low quiescent power during system sleep modes. |
| Endurance | 10,000 program/erase cycles per sector - supports field firmware updates over product lifetime. |
| Operating Temperature | –40°C to +85°C industrial range - validated for deployment in automotive body control modules and industrial PLCs. |
Pinout & Package
AT29BV010A-12TI is available in 32-lead PLCC (32J) and TSOP (32T) packages. Pin functions are identical across both packages and fully compatible with standard 8-bit parallel memory buses.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 131,072-word addressing; A0–A6 select byte within 128-byte sector during programming. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; I/O7 used for DATA polling, I/O6 for Toggle Bit status indication during program/erase. |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high disables outputs and enters standby mode (40 µA). |
| OE | Output Enable | Active-low output control; used with CE to manage bus contention; high forces outputs to high-impedance state. |
| WE | Write Enable | Active-low write strobe; initiates byte load during programming; combined with CE for software protection sequence timing. |
| NC | No Connect | Two unconnected pins (PLCC pin 13 & 32, TSOP pin 1 & 32); must remain floating - no pull-up/down required. |
| VCC | Power Supply | 2.7V–3.6V main supply; internal VCC sense circuitry inhibits programming if voltage drops below ~2.0V. |
| GND | Ground Reference | Signal and power ground reference; decoupling capacitor (0.1 µF) required near VCC pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h→2AAAh→5555h) prevents accidental writes - essential for field-upgradable firmware integrity. |
| Boot Block Lockout | Independent enable/disable of programming for first/last 8K-byte regions - secures bootloader code against corruption during application updates. |
| Sector Programming | 128-byte granularity with internal latching - allows partial rewrites without erasing entire device; reduces update latency vs. chip-erase methods. |
| Program Status Detection | Dual-mode (DATA polling on I/O7 + Toggle Bit on I/O6) - provides flexible, non-intrusive verification without dedicated status registers or extra pins. |
| Hardware Write Inhibit | VCC sense, 10 ms power-on delay, and 15 ns noise filtering on WE/CE - eliminates need for external reset supervisors in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF010-70-4C-NHE | 70 ns access time, 3.0V–3.6V only, no boot block lockout, 100K endurance cycles | Lacks sector lockout and VCC sense protection; suited for cost-sensitive consumer designs where security is secondary | Choose when faster read speed is prioritized over industrial-grade write protection and temperature range. |
| MX29LV100CTTC-70G | 70 ns access, 2.7V–3.6V, 100K endurance, top/bottom boot block configuration but no software lockout enable | Hardware-configured boot blocks only; no software-activated lockout - requires PCB-level strap options for protection | Prefer when board-level configuration suffices and software-controlled lockout flexibility is unnecessary. |
Compared with SST39VF010-70-4C-NHE and MX29LV100CTTC-70G, the AT29BV010A-12TI uniquely combines industrial temperature operation, software-activatable boot block lockout, and VCC-sense hardware protection - making it the only option among the three qualified for safety-critical embedded firmware storage where accidental writes must be prevented under all conditions.

FAQ
What is the guaranteed read access time for AT29BV010A-12TI?
The AT29BV010A-12TI guarantees a maximum read access time of 120 ns under industrial temperature conditions (–40°C to +85°C) and 2.7V–3.6V supply. This value is specified in the AC Read Characteristics table and applies to both PLCC and TSOP packages. The "-12" suffix explicitly denotes this 120 ns timing grade, distinguishing it from slower variants like -15 (150 ns) or -20 (200 ns).
Does AT29BV010A-12TI require high-voltage programming signals?
No, the AT29BV010A-12TI does not require high-voltage programming signals. It operates with a single 2.7V–3.6V supply for both read and write operations. Programming is enabled only after a specific three-byte software unlock sequence (AAh→55h→A0h), and internal circuitry handles erase and program timing - eliminating external VPP pins or charge pumps required by older Flash technologies.
How is program completion detected on AT29BV010A-12TI?
Program completion on AT29BV010A-12TI is detected using two hardware-supported methods: DATA polling on I/O7 (complement of loaded data until completion, then true data) and Toggle Bit behavior on I/O6 (toggling between 0/1 during programming, stabilizing upon completion). Both methods operate without halting the host processor and require no additional status registers or pins.
Can the boot blocks of AT29BV010A-12TI be locked independently?
Yes, the AT29BV010A-12TI features two independent 8K-byte boot blocks - one at the lowest addresses (0x00000–0x01FFF) and one at the highest (0xFE000–0xFFFFF) - each with separately activatable programming lockout. Activation requires a seven-command software sequence per block, and once enabled, neither block can be erased or programmed, while remaining memory remains fully writable.
What package options are available for AT29BV010A-12TI?
The AT29BV010A-12TI is offered in two industry-standard packages: 32-lead Plastic J-Leaded Chip Carrier (PLCC-32, suffix "J") and 32-lead Thin Small Outline Package (TSOP-32, suffix "T"). Both share identical pinouts and electrical specifications; the "-TI" ordering code specifically denotes the TSOP-32 package in industrial temperature grade, while "-JI" indicates PLCC-32 in the same grade.
