Product details
Overview
AT29BV010A-15TC 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, sector-based reprogramming (1024 × 128-byte sectors), and dual 8K-byte boot blocks with independent programming lockout. It supports in-system reprogrammability without high-voltage programming and is used in embedded firmware storage for industrial controllers and legacy BIOS modules.
For engineers reviewing the AT29BV010A-15TC datasheet, AT29BV010A-15TC pinout, AT29BV010A-15TC application, or AT29BV010A-15TC equivalent, key selection criteria include its 150 ns read timing, software data protection sequence (AAh/55h/A0h), DATA polling/Toggle Bit program status detection, 2.7V-only operation, and PLCC-32 package compatibility with legacy socketed designs.
Technical Context
The AT29BV010A-15TC implements a sector-erase-and-program architecture with internal address/data latches for 128-byte loads, eliminating external buffering during write cycles. Its software data protection requires a three-byte command sequence (5555h/2AAAh/5555h) before each sector program, and hardware safeguards include VCC sense (<2.0V inhibit), noise filtering (<15 ns pulse rejection), and CE/OE/WE control-state locking.
It features dual boot blocks (0x0000–0x1FFF and 0xFE000–0xFFFF) with independent lockout activation via a seven-command algorithm, enabling secure system startup code storage. Program completion is verified via I/O7 DATA polling or I/O6 Toggle Bit behavior-both detectable at any point during the ≤20 ms internal cycle without halting host bus activity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - directly maps to 128 KB firmware image storage. |
| Read Access Time | 150 ns max - enables direct interface with 6–8 MHz microcontrollers without wait states. |
| Supply Voltage | 2.7V to 3.6V single supply - eliminates need for dedicated 5V programming voltage; compatible with battery-backed systems. |
| Active Current | 15 mA max at 3.6V/5 MHz - supports low-power operation in always-on embedded hosts. |
| Standby Current | 40 µA CMOS standby (commercial temp) - suitable for long-duration sleep modes in field-deployed equipment. |
| Endurance | >10,000 program/erase cycles per sector - sufficient for field firmware updates over 5+ year product lifecycles. |
| Operating Temp | -40°C to +85°C (industrial grade) - qualified for use in motor drives, PLCs, and outdoor telecom units. |
Pinout & Package
AT29BV010A-15TC is packaged in a 32-lead Plastic Leaded Chip Carrier (PLCC-32), pin-compatible with JEDEC MS-016 AE variant. The package features gull-wing leads, 1.27 mm pitch, and a 12.3–12.6 mm × 14.9–15.1 mm body size with 3.2–3.6 mm height.
| 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 | Bi-directional Data Bus | 8-bit parallel data path for read/write; I/O7 provides DATA polling status, I/O6 provides Toggle Bit status. |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high disables outputs and enters CMOS standby mode. |
| 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; controls byte loading during sector programming; OE must be high when WE and CE are both low. |
| VCC | Power Supply | 2.7–3.6V main supply; internal VCC sense circuit inhibits programming if voltage drops below ~2.0V. |
| GND | Ground Reference | Signal and power ground reference; decoupling capacitor required near VCC pin for stable operation. |
| NC | No Connect | Two unconnected pins (PLCC pin 13 and pin 31); must remain floating - no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h/2AAAh/5555h) required before every sector program - prevents accidental writes during power-up/down or noise events. |
| Dual Boot Block Lockout | Independent 8K-byte lockout for lower (0x0000–0x1FFF) and upper (0xFE000–0xFFFF) blocks - secures bootloader code against corruption while allowing application updates elsewhere. |
| Sector Program Architecture | 1024 × 128-byte sectors with internal latching - allows host CPU to release address/data bus after loading 128 bytes, improving system concurrency. |
| Program Status Detection | Hardware-supported DATA polling (I/O7) and Toggle Bit (I/O6) - eliminates need for fixed delay timers or external status monitoring logic. |
| CMOS/TTL Input Compatibility | Inputs accept 0–5.5V regardless of VCC level - simplifies interfacing with mixed-voltage systems (e.g., 5V microcontrollers driving 3.3V Flash). |
Applications
| Industrial PLC Firmware Storage | Legacy BIOS/UEFI Module |

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 read access, 3.3V-only supply, same 1 Mbit density and PLCC-32 package. | Lacks boot block lockout; uses different software unlock sequence (5555h/2AAAh/5555h → 5555h/2AAAh/20h). | Preferred where faster read timing is critical and boot security is managed externally. |
| MX29LV160BTC-90G | 16 Mbit density, 90 ns read, TSOP-48 package; includes CFI query support and enhanced sector protection. | Not pin-compatible; requires PCB redesign; supports wider voltage range (2.7–3.6V) but lacks PLCC-32 footprint. | Recommended for new designs needing higher density and standardized command sets, not drop-in replacement. |
Compared with SST39VF010-70-4C-NHE and MX29LV160BTC-90G, the AT29BV010A-15TC offers unique boot block lockout and PLCC-32 compatibility for legacy-replacement scenarios, while trading speed for proven field reliability in industrial firmware storage.

FAQ
What is the maximum read access time specified for the AT29BV010A-15TC?
The AT29BV010A-15TC 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 timing applies across the full commercial temperature range (0°C to +70°C) and 2.7V–3.6V supply, ensuring deterministic performance in microcontroller bus interfaces without added wait states. The "-15" suffix explicitly denotes this 150 ns speed grade.
Does the AT29BV010A-15TC require high-voltage programming signals?
No, the AT29BV010A-15TC operates with a single 2.7V–3.6V supply for both read and write operations - no external 12V or 5V programming voltage is needed. Programming is enabled only after a software unlock sequence (5555h/2AAAh/5555h), and internal circuitry handles erase-and-program sequencing automatically. This eliminates high-voltage generator circuitry and simplifies system design.
How is program completion detected on the AT29BV010A-15TC?
Program completion on the AT29BV010A-15TC is detected using either DATA polling on I/O7 (complement of loaded data until completion, then true data) or the Toggle Bit on I/O6 (toggles between 0/1 during programming, stabilizes afterward). Both methods are hardware-automated and can be polled at any time during the ≤20 ms internal cycle - no fixed delays or external timers are required.
What is the purpose of the two NC pins on the AT29BV010A-15TC PLCC-32 package?
The AT29BV010A-15TC PLCC-32 package has two NC (No Connect) pins - pin 13 and pin 31 - which are electrically isolated from internal circuitry and must remain unconnected. These pins exist for mechanical symmetry and package standardization per JEDEC MS-016 AE; routing traces or applying pull-ups/pull-downs to them may cause signal integrity issues or violate thermal/mechanical specifications.
Can the AT29BV010A-15TC be used as a direct replacement for the AT29C010A?
No, the AT29BV010A-15TC is not a direct replacement for the AT29C010A. While both are 1 Mbit Flash devices in PLCC-32 packages, the AT29C010A requires 5V for programming and uses different command sequences and timing. The AT29BV010A-15TC operates at 2.7–3.6V only and implements distinct software data protection and boot block lockout features - firmware and hardware interfaces must be validated for compatibility before substitution.
