Product details
Overview
AT29C010A-15TC from Atmel is a 1 Mbit (128K × 8) 5V-only Flash memory IC used for nonvolatile code and data storage in embedded systems, supporting in-system reprogramming via sector-based erase-and-program operations. It delivers 150 ns read access time, 10 ms sector program cycle time, and features hardware/software data protection, two 8K-byte boot blocks with independent lockout, and CMOS/TTL-compatible I/O.
For engineers reviewing the AT29C010A-15TC datasheet, AT29C010A-15TC pinout, AT29C010A-15TC application, or AT29C010A-15TC equivalent, key selection considerations include its 150 ns access timing, TSOP-32 package compatibility, sector-level programming architecture, boot block lockout behavior, and 5V-only operation without high-voltage programming signals.
Technical Context
The AT29C010A-15TC implements a sector-erase Flash architecture with 1024 × 128-byte sectors, internal address/data latches for full-sector loading, and automatic internal erase-and-program sequencing triggered by WE/CE control. Its dual 8K boot blocks reside at addresses 0x00000–0x01FFF and 0x1E000–0x1FFFF, each independently lockable via a 7-command software algorithm.
Operation relies on standard parallel bus control: CE and OE low + WE high enables read mode; WE low + CE low + OE high initiates byte load; DATA polling on I/O7 or toggle-bit detection on I/O6 signals program completion. Hardware protection includes VCC sense (<3.8V inhibits programming), 5 ms power-on delay, and noise filtering on WE/CE inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - supports firmware storage for 8-bit microcontrollers and boot loaders. |
| Read Access Time | 150 ns max - defines minimum clock period for reliable read cycles in 6–8 MHz CPU interfaces. |
| Sector Program Time | 10 ms typical - determines worst-case latency when updating firmware sections or configuration data. |
| Endurance | >10,000 program/erase cycles per sector - ensures field-upgradable reliability over multi-year product lifetimes. |
| Supply Voltage | 5V ±10% - eliminates need for dedicated programming voltage rails; compatible with legacy 5V logic systems. |
| Standby Current | 100 µA (CMOS, commercial temp) - enables low-power retention in battery-backed or sleep-mode applications. |

Pinout & Package
AT29C010A-15TC is housed in a 32-lead Thin Small Outline Package (TSOP, Type I, JEDEC MO-142 BD), 8 mm × 20 mm body, 0.5 mm lead pitch, gull-wing leads, and pin 1 identifier notch. Pin functions are electrically identical across PLCC, PDIP, and TSOP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus; A0–A6 select byte within 128-byte sector, A7–A16 select sector address. |
| CE | Chip Enable | Active-low chip select; must be low for read, program, or byte load; high disables outputs and enters standby. |
| OE | Output Enable | Active-low output control; used with CE to gate data bus during reads; high forces I/O pins to high-Z. |
| WE | Write Enable | Active-low write control; initiates byte load and program cycles; combined with CE and OE defines operation mode. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; carries input data during programming and output data during reads; supports DATA polling on I/O7 and toggle-bit detection on I/O6. |
| VCC | Power Supply | +5V ±10% supply; powers core logic and I/O buffers; internally regulated for stable programming voltage. |
| GND | Ground Reference | Signal and power ground reference for all I/O and internal circuitry; requires low-impedance PCB connection. |
| NC | No Connect | Two unconnected pins (positions 6 and 9 in TSOP top view); must remain floating - no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle sector erase-and-program | Eliminates external high-voltage generators; enables field firmware updates using only 5V supply and standard logic-level control signals. |
| Boot block lockout (2 × 8K) | Prevents accidental overwrite of critical boot code stored in lowest/highest 8K segments - essential for fail-safe system recovery. |
| Hardware + software data protection | VCC sensing, 5 ms power-on delay, and 3-byte unlock sequence prevent spurious writes during power transients or software glitches. |
| DATA polling & toggle-bit detection | Enables real-time program status monitoring without timers or interrupts - simplifies host controller firmware for reliable flash management. |
| CMOS/TTL I/O compatibility | Supports direct interfacing with both 5V CMOS and TTL microcontrollers, FPGAs, and ASICs without level-shifting components. |
| 10,000-cycle endurance | Validated sector-level rewrite capability ensures long-term reliability in applications requiring frequent parameter or calibration updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-150EC | 3V/5V tolerant (3.0–3.6V or 4.75–5.25V), 150 ns access, 1 Mbit, PLCC-32 only - lacks TSOP option and boot block lockout. | Requires separate 3.3V supply or level shifters in 5V systems; no hardware-enforced boot protection. | Select if migrating to lower-voltage systems or needing extended temperature range (-55°C to +125°C). |
| MX29LV160CBTI-15G | 3V-only, 16 Mbit (2M × 8), 150 ns, TSOP-48 - higher density, different pinout, CFI-compliant command set. | Not pin-compatible; requires PCB redesign and firmware adaptation for command interface and sector map. | Select for new designs requiring larger code space and industry-standard CFI support, not for drop-in replacement. |
Compared with AM29LV010B-150EC and MX29LV160CBTI-15G, the AT29C010A-15TC offers unique 5V-only simplicity, TSOP-32 footprint, and dual boot block lockout - making it optimal for cost-sensitive industrial upgrades where legacy 5V infrastructure and firmware security are priorities.

FAQ
What is the maximum read access time specified for the AT29C010A-15TC?
The AT29C010A-15TC has a maximum read access time of 150 ns, as confirmed by its ordering code suffix "-15" and AC Read Characteristics table. This value applies across the full industrial temperature range (-40°C to +85°C) and defines the guaranteed time from address stabilization to valid data on I/O0–I/O7 when CE and OE are asserted low and WE is high. The AT29C010A-15TC meets this spec under VCC = 5V ±10% conditions.
Does the AT29C010A-15TC support in-system programming without high-voltage signals?
Yes, the AT29C010A-15TC supports full in-system programming using only a single 5V supply - no external 12V or 13V programming voltage is required. Programming is initiated via standard logic-level WE and CE pulses, with internal charge pumps generating necessary voltages. This capability is intrinsic to the AT29C010A-15TC's architecture and documented in its "5-volt Only Reprogramming" feature list and Program Cycle Waveforms.
How many boot blocks does the AT29C010A-15TC have, and what is their size?
The AT29C010A-15TC contains two dedicated boot blocks, each 8K bytes (65,536 bits) in size. One resides at the lowest addresses (0x00000–0x01FFF), the other at the highest (0x1E000–0x1FFFF). Both support independent software-enabled programming lockout, and this configuration is fixed for the AT29C010A-15TC - not configurable or removable via hardware or firmware.
What package type is used for the AT29C010A-15TC?
The AT29C010A-15TC uses a 32-lead Thin Small Outline Package (TSOP), designated as "32T" in Atmel's ordering information. It conforms to JEDEC MO-142, Variation BD, with dimensions 8 mm × 20 mm, 0.5 mm lead pitch, and gull-wing leads. This package is distinct from the PLCC-32 (32J) and PDIP-32 (32P6) variants offered for other AT29C010A speed grades.
Can the AT29C010A-15TC be programmed sector-by-sector or only as a whole chip?
The AT29C010A-15TC supports sector-by-sector programming only - it does not implement a chip-erase mode by default. While a 6-byte software chip erase command exists, it is disabled if either boot block lockout is activated. Standard operation requires loading 128 bytes into a sector (using WE/CE pulses) followed by automatic internal erase-and-program; partial-sector writes leave unloaded bytes indeterminate. This behavior is fundamental to the AT29C010A-15TC's architecture.
