Product details
Overview
AT29BV010A-15JU-T from Microchip Technology (formerly Atmel) is a 1-Mbit (128K × 8) single-supply Flash memory IC used for nonvolatile code and data storage in embedded systems. It operates from 2.7V to 3.6V, delivers 150 ns read access time, supports sector-based reprogramming with 1024 × 128-byte sectors, and features hardware and software data protection. It is commonly deployed in industrial microcontroller boot loaders and firmware update storage.
For engineers reviewing the AT29BV010A-15JU-T datasheet, AT29BV010A-15JU-T pinout, AT29BV010A-15JU-T application, or AT29BV010A-15JU-T equivalent, key selection criteria include its 2.7–3.6V single-supply operation, 150 ns read timing, 20 ms max sector program cycle, boot block lockout capability, and PLCC-32 packaging compatibility.
Technical Context
The AT29BV010A-15JU-T implements a sector-erase architecture with internal address/data latches for 128-byte loads, enabling microprocessor-speed data capture before autonomous erase-and-program execution. Its dual-line chip enable (CE) and output enable (OE) control allows flexible bus contention management during read operations.
Programming relies on a three-byte software unlock sequence (AAh/55h/A0h) followed by byte-by-byte loading within 150 µs windows; DATA polling on I/O7 or toggle-bit monitoring on I/O6 provides end-of-program detection. Hardware protections include VCC sense (<2.0V inhibit), 10 ms power-on delay, and noise filtering for WE/CE pulses <15 ns.
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 of firmware or configuration storage. |
| Read Access Time | 150 ns max - ensures compatibility with 6–7 MHz microcontroller bus timing without wait states. |
| Supply Voltage | 2.7V to 3.6V single supply - eliminates need for charge pumps or auxiliary voltage rails in battery-powered or low-voltage systems. |
| Active Current | 15 mA at 3.6V, 5 MHz - enables low-power operation in portable or energy-constrained embedded designs. |
| Standby Current | 50 µA CMOS standby - supports ultra-low-power sleep modes in always-on control applications. |
| Sector Size | 128 bytes per sector (1024 total sectors) - balances granularity for partial updates against overhead of sector management logic. |
| Endurance | 10,000 program/erase cycles per sector - supports field firmware upgrades over multi-year product lifecycles. |
| Boot Blocks | Two 8K-byte blocks with independent lockout - protects critical bootloader code from accidental overwrite during application updates. |
Pinout & Package
AT29BV010A-15JU-T is packaged in a 32-lead Plastic J-Leaded Chip Carrier (PLCC), JEDEC MS-016 variation AE compliant, with 1.27 mm pitch and 12.32 mm × 14.86 mm body dimensions. Pin 1 identifier is a corner 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 during programming. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface compatible with standard microcontroller data buses; supports true read/write and DATA polling on I/O7. |
| CE | Chip Enable | Active-low device select; when high, places outputs in high-impedance state and disables internal logic to minimize power draw. |
| OE | Output Enable | Active-low read control; used with CE to manage bus contention and support multiplexed memory architectures. |
| WE | Write Enable | Active-low write control; initiates byte load cycles during programming and must be synchronized with CE per AC timing specs. |
| NC | No Connect | Two unconnected pins (PLCC pins 13 and 31); must remain floating - no external pull-up/down or routing required. |
| VCC | Power Supply | Single 2.7–3.6V supply input; powers all internal logic, charge pumps, and I/O buffers - no separate VPP required. |
| GND | Ground | Reference return path for VCC and all signals; requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h/2AAAh/5555h) prevents accidental writes - eliminates need for hardware write-protect jumpers or switches. |
| Boot Block Lockout | Independent 8K-byte lockout for lower and upper memory blocks - secures bootloader code while allowing application partition updates. |
| DATA Polling & Toggle Bit | I/O7 complement polling and I/O6 toggle-bit status reporting enable interrupt-driven programming completion detection without timer overhead. |
| Single-Cycle Sector Reprogram | Internal erase-and-program automation after 128-byte load - removes requirement for external erase commands or timing-critical host sequencing. |
| CMOS/TTL-Compatible I/O | Input thresholds (VIL = 0.6V, VIH = 2.0V) and output drive (VOH = 2.4V @ -100 µA) ensure interoperability with both 3.3V and 5V legacy microcontrollers. |
| Green Packaging | Pb/Halide-free PLCC-32 package - meets RoHS Directive 2011/65/EU and facilitates compliance in environmentally regulated markets. |

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, 3.0–3.6V supply only, no boot block lockout, TSOP-32 package | Lacks hardware-protected boot sectors; requires tighter VCC regulation and offers faster read but less robust programming safeguards | Select when maximum read speed is prioritized over field-update security and board layout accommodates TSOP footprint |
| MX29LV160DBTI-90G | 16 Mbit density, 90 ns read, 2.7–3.6V, 16K/64K boot sectors, TSOP-48 package | Higher density and asymmetric boot block sizes; incompatible pinout and sector addressing scheme | Choose for scalable designs needing larger firmware capacity and enhanced boot flexibility, accepting PCB redesign and firmware adaptation |
Compared with AT29BV010A-15JU-T, SST39VF010-70-4C-NHE trades boot security and voltage margin for raw speed, while MX29LV160DBTI-90G expands capacity and boot architecture at the cost of pin compatibility and firmware porting effort - neither is pin-compatible, but both serve overlapping embedded Flash use cases.

FAQ
What is the maximum read access time specified for the AT29BV010A-15JU-T?
The AT29BV010A-15JU-T has a maximum read access time of 150 ns, as confirmed in the AC Read Characteristics table for the -15 speed grade. This parameter defines the delay from address stabilization or CE/OE assertion to valid data appearing on I/O0–I/O7, and is guaranteed across the full industrial temperature range (-40°C to +85°C) and 2.7–3.6V supply.
Does the AT29BV010A-15JU-T require a high-voltage programming supply?
No, the AT29BV010A-15JU-T does not require a high-voltage programming supply. It operates with a single 2.7V to 3.6V supply for both read and write operations. Programming is enabled via a software unlock sequence, and internal circuitry handles all voltage generation - eliminating the need for external VPP pins or charge pumps.
How many sectors does the AT29BV010A-15JU-T contain, and what is the size of each sector?
The AT29BV010A-15JU-T contains 1024 sectors, each sized at 128 bytes. This sector organization is fixed and used for all erase and program operations. During programming, the full 128-byte sector must be loaded before internal erase-and-program execution begins - partial sector writes are not supported.
What packaging type is used for the AT29BV010A-15JU-T, and what does the 'JU' suffix indicate?
The AT29BV010A-15JU-T uses a 32-lead Plastic J-Leaded Chip Carrier (PLCC) package. The 'JU' suffix denotes the PLCC-32 variant with green (Pb/Halide-free) packaging, per Atmel's ordering information. This differs from the 'TU' suffix, which indicates the TSOP-32 version.
Can the boot blocks of the AT29BV010A-15JU-T be independently locked, and how is lockout verified?
Yes, the two 8K-byte boot blocks (lower: 0x0000–0x1FFF; upper: 0xE000–0xFFFF) support independent programming lockout. Lockout status is verified by entering Software Product Identification mode and reading address 0x0002 (lower block) or 0x1FFF2 (upper block): FEh means unlocked, FFh means locked. Once activated, lockout is irreversible and disables chip erase.
