Product details
Overview
AT29BV010A-15TI 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 industrial temperature range (−40°C to +85°C). It implements software data protection, dual 8K boot blocks with independent lockout, and DATA polling/toggle-bit programming status detection for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the AT29BV010A-15TI datasheet, AT29BV010A-15TI pinout, AT29BV010A-15TI application, or AT29BV010A-15TI equivalent, key selection criteria include sector-based reprogrammability, CMOS/TTL-compatible I/O, low 40 µA standby current, and PLCC-32 packaging - all critical for legacy industrial controller upgrades and in-system firmware updates.
Technical Context
The AT29BV010A-15TI uses Atmel's nonvolatile CMOS EEPROM process to deliver 128K × 8 organization with sector-erase architecture: 1024 sectors of 128 bytes each, plus two dedicated 8K boot blocks. Programming requires a three-byte unlock sequence (AAh/55h/A0h) followed by byte-load cycles within 150 µs intervals, with internal erase-and-program automation.
It supports standard EPROM-like read operation (CE/OE low, WE high), hardware write inhibition via VCC sense (<2.0V), noise filtering (<15 ns pulses rejected), and dual programming status detection: DATA polling on I/O7 and toggle-bit behavior on I/O6. Boot block lockout is enabled via a seven-command algorithm and disables chip erase when activated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - fits firmware images up to 128 KB without external banking logic. |
| Read Access Time | 150 ns max - enables direct interface with 5–8 MHz microcontrollers without wait states. |
| Supply Voltage | 2.7V–3.6V single supply - eliminates need for charge pumps or dual-rail regulators in battery-powered or low-voltage systems. |
| Active Current | 15 mA max at 5 MHz - supports burst reads in power-constrained edge devices. |
| Standby Current | 40 µA max (CMOS mode) - extends battery life in always-on monitoring nodes. |
| Sector Size | 128 bytes per sector - balances granularity for partial firmware updates against overhead of sector management. |
| Endurance | 10,000 program/erase cycles per sector - sufficient for field-upgradable bootloader and configuration storage. |
| Temperature Range | −40°C to +85°C - qualified for industrial control cabinets and outdoor telemetry enclosures. |
Pinout & Package
AT29BV010A-15TI is packaged in a 32-lead Plastic Leaded Chip Carrier (PLCC), pin-compatible with industry-standard 32J footprint. The package features J-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 128K-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 state forces outputs to high-impedance and inhibits programming. |
| OE | Output Enable | Active-low output control; used with CE to prevent bus contention; must be high during programming. |
| WE | Write Enable | Active-low write strobe; controls latching of address/data during byte load; low pulse initiates programming sequence. |
| VCC | Power Supply | 2.7–3.6V main supply; internal VCC sense circuitry disables programming if voltage drops below ~2.0V. |
| GND | Ground Reference | Signal and power return; decoupling capacitor required near VCC pin for stable read/write timing. |
| NC | No Connect | Two unconnected pins (PLCC pin 13 and 32); must remain floating - no routing or grounding allowed. |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h/2AAAh/5555h) required before any sector programming - prevents accidental firmware corruption during power transients or noise events. |
| Dual Boot Block Lockout | Independent 8K-byte lockout for lower (0x0000–0x1FFF) and upper (0x1E000–0x1FFFF) memory regions - secures bootloader code from overwrite while allowing application updates elsewhere. |
| Internal Sector Erase | Automatic erase prior to programming - eliminates separate erase command and simplifies host firmware logic. |
| DATA Polling & Toggle Bit | Real-time program status via I/O7 complement read or I/O6 toggling - enables deterministic polling loops without fixed delays or external timers. |
| CMOS/TTL-Compatible I/O | Input thresholds (VIL ≤ 0.6V, VIH ≥ 2.0V) and output drive (VOH ≥ 2.4V @ −100 µA) support direct interfacing with both 3.3V and 5V microcontrollers. |
| 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 writes. |

FAQ
What is the maximum read access time specified for the AT29BV010A-15TI?
The AT29BV010A-15TI 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 2.7–3.6V supply, enabling direct interface with mid-speed microcontrollers without wait-state insertion. The "15" in the part number explicitly denotes this 150 ns speed grade.
Does the AT29BV010A-15TI require high-voltage programming signals?
No, the AT29BV010A-15TI operates with a single 2.7–3.6V supply for both read and write operations - no external 12V or 5V programming voltage is needed. Programming is initiated via a software unlock sequence (5555h/2AAAh/5555h), after which byte loads occur at core logic voltage. Hardware protection circuits (VCC sense, noise filtering) ensure robustness against spurious writes during normal operation.
How does the boot block lockout feature work on the AT29BV010A-15TI?
The AT29BV010A-15TI contains two 8K-byte boot blocks - one at the lowest addresses (0x0000–0x1FFF) and one at the highest (0x1E000–0x1FFFF). Each can be independently locked using a seven-command enable algorithm. Once locked, that block becomes permanently read-only: no erasure or programming is possible, and chip erase is disabled. Lock status is verified by reading address 00002h (lower block) or 1FFF2h (upper block).
Can the AT29BV010A-15TI be used as a direct replacement for the AT29BV010A-15JC?
Yes - the AT29BV010A-15TI and AT29BV010A-15JC share identical electrical specifications, timing parameters, and PLCC-32 pinout. The only difference is temperature grading: "TI" denotes industrial range (−40°C to +85°C), while "JC" is commercial (0°C to +70°C). Both use the same 32J package and are functionally interchangeable in industrial designs where extended temperature operation is required.
What programming status detection methods does the AT29BV010A-15TI support?
The AT29BV010A-15TI supports two hardware-verified programming status detection methods: DATA polling (monitoring complement-to-data on I/O7) and toggle-bit detection (observing I/O6 toggling between 0 and 1). Both methods allow the host microcontroller to poll asynchronously without fixed delays, and either can be used independently. The device guarantees these behaviors across all operating conditions defined in the datasheet.
