Product details
Overview
AT29C010A-15JC from Atmel is a 1 Mbit (128K × 8) 5V-only Flash memory IC used for nonvolatile code and data storage in embedded systems. It delivers 150 ns read access time, supports sector-based reprogramming with 1024 × 128-byte sectors, includes dual 8K-byte boot blocks with independent lockout, and operates across commercial temperature range (0°C to 70°C) in PLCC-32 package.
For engineers reviewing the AT29C010A-15JC datasheet, AT29C010A-15JC pinout, AT29C010A-15JC application, or AT29C010A-15JC equivalent, this page provides verified functional identity, validated PLCC-32 pin mapping, confirmed sector-program architecture, hardware/software data protection implementation details, and real-world boot-code storage use cases - all grounded in Atmel's official Rev. 0394F–FLASH–02/03 specification.
Technical Context
The AT29C010A-15JC implements a sector-erase-and-program Flash architecture requiring no external high-voltage supply: all operations execute under single 5V ±10% VCC. Its internal latching logic captures full 128-byte sectors during byte-load cycles, enabling bus release for concurrent system activity while programming proceeds autonomously via on-chip timer.
Hardware data protection enforces VCC sense (<3.8V inhibit), 5 ms power-on delay, and noise filtering (<15 ns pulse rejection); software protection uses three-command sequences (e.g., AAh/55h/A0h) to enable/disable write locks. Boot block lockout is independently configurable for lower (0x00000–0x01FFF) and upper (0x1E000–0x1FFFF) 8K segments, disabling chip erase if either is activated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8 bits) - sufficient for firmware images up to 128 KB in size. |
| Read Access Time | 150 ns - defines maximum clock rate for synchronous read interfaces (e.g., ≤6.7 MHz for wait-state-free CPU access). |
| Sector Size | 128 bytes × 1024 sectors - enables fine-grained updates without erasing entire device; critical for field firmware patches. |
| Program Cycle Time | 10 ms per sector - determines minimum time between successive sector writes; impacts OTA update latency. |
| VCC Supply Range | 5V ±10% - compatible with standard TTL/CMOS logic rails; eliminates need for dedicated programming voltage regulators. |
| Endurance | >10,000 program/erase cycles per sector - supports long-term field upgrades in industrial controllers and telecom equipment. |
| Standby Current | 100 µA (CMOS) - enables low-power retention in battery-backed systems during sleep modes. |
Pinout & Package
AT29C010A-15JC is packaged in 32-lead Plastic J-Leaded Chip Carrier (PLCC-32), compliant with JEDEC MS-016 Variation AE. Pin 1 identifier is located at top-left corner when notch faces upward; body dimensions are 12.57 mm × 15.11 mm × 3.56 mm (L×W×H).
| 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. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; supports DATA polling on I/O7 and Toggle Bit detection on I/O6 during programming. |
| CE | Chip Enable | Active-low global select; must be low for read, program, or identification mode; high disables outputs to prevent bus contention. |
| OE | Output Enable | Active-low output control; used with CE to gate read data; high forces outputs to high-impedance state. |
| WE | Write Enable | Active-low command input; initiates byte loads and sector programming; combined with CE/OE to define operation mode. |
| VCC | Power Supply | +5V ±10% main supply; powers core logic and I/O buffers; internally monitored for hardware write inhibition below 3.8V. |
| GND | Ground Reference | Signal and power return path; decoupling capacitor required near VCC pin for stable operation. |
| NC | No Connect | Two unconnected pins (PLCC positions 6 and 13); must remain floating - no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8K-byte boot blocks with independent lockout | Enables secure storage of bootloader code in fixed memory regions; prevents accidental overwrite during application firmware updates. |
| Hardware + software data protection | VCC sensing, 5 ms power-on delay, and 3-byte command sequences (AAh/55h/A0h) jointly eliminate unintended writes during power transitions or noise events. |
| DATA polling and Toggle Bit (I/O6) | Allows real-time program completion detection without timers or interrupts - reduces host CPU overhead during firmware flashing. |
| Single-cycle sector erase-and-program | Eliminates separate erase step: loading 128 bytes automatically triggers internal sector erase followed by programming - simplifies host driver logic. |
| CMOS/TTL-compatible I/O | Supports direct interfacing with legacy microcontrollers (e.g., 8051, Z80) and modern FPGAs without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160BTC-90G | 16 Mbit density, 3.0V–3.6V supply, 90 ns access, TSOP-48 package | Higher density and lower voltage; requires level translation for 5V systems | Select when migrating to 3.3V platforms and needing larger firmware capacity; not drop-in compatible due to voltage and pinout mismatch. |
| AM29LV010B-120EC | 1 Mbit, 3.0V–3.6V supply, 120 ns access, PDIP-32 package | Same density but 3.3V-only; lacks boot block lockout and software data protection | Choose for cost-sensitive 3.3V designs where simplified protection suffices; requires PCB redesign for voltage rail and footprint. |
Compared with MX29LV160BTC-90G and AM29LV010B-120EC, the AT29C010A-15JC uniquely combines 5V-only operation, dual boot block lockout, and hardware/software write protection in a PLCC-32 package - making it irreplaceable for maintaining legacy 5V embedded systems requiring secure, field-upgradable firmware storage.

FAQ
What is the maximum operating temperature range for the AT29C010A-15JC?
The AT29C010A-15JC is rated for commercial temperature operation from 0°C to 70°C. This is explicitly defined in the Ordering Information table of the official datasheet (Rev. 0394F–FLASH–02/03), where the "-15JC" suffix denotes the commercial-grade PLCC-32 variant. Industrial variants (e.g., AT29C010A-15JI) support -40°C to +85°C, but the AT29C010A-15JC itself is limited to 0°C–70°C.
Does the AT29C010A-15JC require external high-voltage programming signals?
No, the AT29C010A-15JC does not require external high-voltage programming signals. As stated in the datasheet Description section, it is a "5-volt-only in-system Flash programmable" device. All programming operations - including sector erase and byte load - are executed using only the standard 5V ±10% VCC supply, with no need for 12V or other elevated voltages. This is enforced by internal hardware protection circuits.
How many sectors does the AT29C010A-15JC contain, and what is the size of each sector?
The AT29C010A-15JC contains exactly 1024 sectors, each sized at 128 bytes. This is confirmed in the Features section of the datasheet: "Sector Program Operation – 1024 Sectors (128 Bytes/sector)". The total memory (131,072 bytes) divided by 128 bytes per sector yields precisely 1024 sectors, and this sector count is invariant across all AT29C010A speed grades and packages, including the AT29C010A-15JC.
Can the boot block lockout feature be disabled after it has been enabled on the AT29C010A-15JC?
No, the boot block lockout feature cannot be disabled once enabled on the AT29C010A-15JC. According to the datasheet section "BOOT BLOCK PROGRAMMING LOCKOUT", activation is permanent: "Once the programming lockout feature has been activated, the data in that block can no longer be erased or programmed". The document provides no algorithm or command sequence to reverse this state, and explicitly states that chip erase is disabled if either boot block is locked - confirming irreversible commitment.
What package type is used for the AT29C010A-15JC, and how is pin 1 identified?
The AT29C010A-15JC uses a 32-lead Plastic J-Leaded Chip Carrier (PLCC-32) package, designated as "32J" in the Ordering Information table. Pin 1 is identified by a notch in the package outline and a chamfered corner; when the notch faces upward, pin 1 is located at the top-left corner of the PLCC body. This mechanical marking is consistent with JEDEC MS-016 Variation AE standards referenced in the Packaging Information section.
