Product details
Overview
AT29BV010A-15JC 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 8KB boot blocks with independent programming lockout. It supports in-system reprogramming without high-voltage inputs and is used in embedded firmware storage for industrial controllers and legacy BIOS modules.
For engineers reviewing the AT29BV010A-15JC datasheet, AT29BV010A-15JC pinout, AT29BV010A-15JC application, or AT29BV010A-15JC equivalent, key selection considerations include its PLCC-32 package, software data protection sequence (AAh/55h/A0h), DATA polling via I/O7, toggle-bit detection on I/O6, and boot-block lockout verification at addresses 00002H and 1FFF2H.
Technical Context
The AT29BV010A-15JC implements a sector-erase-and-program architecture with internal address/data latches for 128-byte loads, eliminating external buffering during programming. Its software data protection requires a three-byte command sequence (AAh→55h→A0h) before each sector program cycle, and hardware protection includes VCC sense (<2.0V inhibit), 10 ms power-on delay, and noise filtering on WE/CE inputs.
Read operation follows EPROM-like timing: CE and OE low with WE high enables output drive; outputs enter high-Z when CE or OE goes high. Programming uses byte-load cycles with ≤150 µs inter-byte timing window, and completion is signaled by DATA polling (I/O7 complement → true data) or toggle-bit behavior (I/O6 toggling → stable).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - directly maps to 16-bit microcontroller data buses without address decoding overhead. |
| Read Access Time | 150 ns max - supports 6.7 MHz bus timing for legacy 80C51 and Z80-based systems without wait states. |
| Supply Voltage | 2.7V–3.6V single supply - enables direct connection to 3.3V logic rails and battery-backed operation in portable equipment. |
| Active Current | 15 mA max at 5 MHz - limits thermal load in compact industrial enclosures with passive cooling. |
| Standby Current | 40 µA CMOS standby (commercial temp) - extends battery life in always-on monitoring nodes over multi-year deployments. |
| Sector Size | 128 bytes per sector (1024 total) - balances granularity for firmware patching against erase-cycle endurance (>10,000 cycles). |
| Boot Blocks | Two 8 KB blocks (lower and upper) with independent lockout - secures bootloader code against accidental overwrite during field updates. |
Pinout & Package
AT29BV010A-15JC is housed in a 32-lead Plastic Leaded Chip Carrier (PLCC-32) package, compliant with JEDEC MS-016 Variation AE, with body dimensions 12.47 mm × 14.99 mm × 3.35 mm (max height) and lead coplanarity ≤0.102 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A7–A16 select sector, A0–A6 select byte within sector during programming. |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high disables outputs to high-Z and forces CMOS standby mode. |
| OE | Output Enable | Active-low output control; used with CE to manage bus contention; high disables outputs regardless of CE state. |
| WE | Write Enable | Active-low write strobe; initiates byte load during programming; must be high for read operations. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit multiplexed data path; I/O7 provides DATA polling status, I/O6 provides toggle-bit status during program/erase. |
| 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 within 10 mm of VCC pin. |
| NC | No Connect | Two unconnected pins (PLCC pin 13 and pin 31); must remain floating - no routing or soldering permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Single 2.7V–3.6V Supply Operation | Eliminates need for dedicated 5V or 12V programming voltages - simplifies power design and enables direct integration into 3.3V-only systems. |
| Software Data Protection Sequence | Three-byte unlock (AAh/55h/A0h) prevents accidental writes during noise events or power transients - no external hardware protection required. |
| Dual Independent Boot Block Lockout | Separate enable commands for lower (0x0000–0x1FFF) and upper (0xE000–0xFFFF) 8KB blocks - allows secure bootloader + fail-safe recovery image storage. |
| DATA Polling & Toggle Bit Detection | I/O7 complement → true data transition and I/O6 toggling provide two independent, software-accessible methods to detect program completion without timers. |
| Internal Sector Erase + Program Timer | Automated erase-before-program eliminates separate erase command step - reduces firmware complexity and guarantees sector consistency. |
| CMOS/TTL Input Compatibility | Inputs accept 0–5.5V logic levels while powered from 2.7V–3.6V - enables direct interfacing with 5V microcontrollers without level shifters. |

FAQ
What is the maximum read access time specified for the AT29BV010A-15JC?
The AT29BV010A-15JC has a maximum read access time of 150 ns, as indicated by the "-15" suffix in its part number. This value is guaranteed across the commercial temperature range (0°C to +70°C) and at VCC = 2.7V–3.6V. The timing applies to the interval from address stabilization or CE/OE assertion to valid data on I/O0–I/O7, and is measured under standard AC test conditions with CL = 5 pF. This specification enables direct replacement of 120 ns EPROMs in many legacy designs with minimal timing margin impact.
Does the AT29BV010A-15JC require high-voltage programming signals?
No, the AT29BV010A-15JC 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 software data protection sequence (AAh to address 5555h, 55h to 2AAAh, then A0h to 5555h), and all subsequent byte loads occur at the same VCC level. Hardware protection features - including VCC sense below 2.0V and noise filtering on WE/CE - further ensure that spurious signals cannot initiate programming, making the AT29BV010A-15JC suitable for in-system reprogramming without external voltage generators.
How is boot block programming lockout verified on the AT29BV010A-15JC?
Boot block programming lockout status on the AT29BV010A-15JC is verified using the Software Product Identification mode. After entering identification mode (AAh/55h/90h sequence), reading address 00002h returns FEh if the lower 8KB boot block is unlocked or FFh if locked; reading 1FFF2h yields the same codes for the upper 8KB block. These status reads are performed with standard read timing and do not alter device state. The AT29BV010A-15JC exits identification mode automatically upon power cycle or via the F0h exit command, returning to normal operation with no side effects.
What package type is used for the AT29BV010A-15JC?
The AT29BV010A-15JC uses a 32-lead Plastic Leaded Chip Carrier (PLCC-32) package, designated as "32J" in Atmel's ordering information. Its dimensions conform to JEDEC MS-016 Variation AE, with a body size of 12.47 mm × 14.99 mm and maximum height of 3.35 mm. Pin 1 is marked by a corner notch, and the package includes two NC pins (pins 13 and 31) that must remain unconnected. This PLCC variant is compatible with standard socketed EPROM carriers used in legacy programming and test fixtures.
Can the AT29BV010A-15JC be used as a direct replacement for the AT29BV010A-12JC?
Yes, the AT29BV010A-15JC can serve as a functional replacement for the AT29BV010A-12JC in most applications, though with a trade-off in read speed: the "-15" version has a 150 ns maximum access time versus 120 ns for the "-12" variant. Both share identical pinout, voltage range (2.7V–3.6V), sector architecture, boot block features, and software command sets. System-level validation is recommended if the original design operates near timing margins, but no PCB or firmware changes are required for substitution in typical industrial or embedded use cases.
