Product details
Overview
AT28C010-15TC from Atmel is a 1-Mbit (128K × 8) paged parallel EEPROM with JEDEC-standard byte-wide pinout, 150 ns read access time, 10 ms maximum page write cycle, and CMOS/TTL-compatible I/O. It operates on single 5V ±10% supply and supports hardware/software data protection for embedded firmware storage in industrial control systems.
For engineers reviewing the AT28C010-15TC datasheet, AT28C010-15TC pinout, AT28C010-15TC application, or AT28C010-15TC equivalent, this device serves as a drop-in replacement for legacy SRAM-based boot memory where nonvolatile retention, page-write efficiency, and robust write-inhibit logic are required.
Technical Context
The AT28C010-15TC implements a paged architecture with a 128-byte internal latch enabling simultaneous writes of 1–128 bytes per cycle. Its internal control timer automates programming after address/data latching, freeing the bus during tWC (≤10 ms).
It features dual write-detection methods-DATA POLLING on I/O7 and TOGGLE BIT on I/O6-and integrates VCC-sense circuitry (write inhibited below 3.8 V), 5 ms power-on delay, and noise filtering (<15 ns pulse rejection) to prevent spurious writes during power transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), organized as 128K words × 8 bits - supports full-addressable byte-level access without external decoding. |
| Read Access Time | 150 ns max - enables direct interface with 6–7 MHz microcontrollers without wait states. |
| Page Write Cycle | 10 ms max - allows burst programming of up to 128 bytes with single WE initiation, reducing host CPU overhead. |
| Supply Voltage | 5 V ±10% - compatible with standard TTL/CMOS logic rails; no auxiliary voltage required. |
| Active Current | 40 mA max - limits thermal load in dense PCB layouts; supports continuous read operation at full speed. |
| Standby Current | 200 µA CMOS - enables low-power retention in battery-backed systems or sleep-mode applications. |
| Endurance | 10,000 write/erase cycles - sufficient for field-upgradable firmware storage with infrequent updates. |
| Data Retention | 10 years at 85°C - validated for industrial temperature range operation without refresh. |
Pinout & Package
AT28C010-15TC is supplied in a 32-lead Plastic Thin Small Outline Package (TSOP), JEDEC MO-142 DD compliant, with 0.5 mm lead pitch and body dimensions 11.8 × 10.0 mm. Pin 1 is located at the top-left corner marked by a beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A7–A16 define page boundaries for 128-byte page writes. |
| 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 writes. |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high state forces outputs to high-Z and inhibits writes. |
| OE | Output Enable | Active-low output control; used with CE to manage bus contention; high disables outputs regardless of CE/WE state. |
| WE | Write Enable | Active-low write strobe; falling edge latches address/data; combined with CE for byte/page write initiation. |
| VCC | Power Supply | +5 V ±10% main supply; powers core logic and I/O buffers; internally monitored for write inhibit. |
| GND | Ground Reference | Signal and power return path; decoupling capacitor required within 10 mm of VCC/GND pins. |
| NC | No Connect | Unbonded pins (TSOP pins 1, 32); must remain unconnected per JEDEC MO-142 DD specification. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Byte-Wide Pinout | Direct replacement for 27C512, 27C010, and 28C256 in existing sockets without layout change. |
| Hardware Write Protection | VCC sense + 5 ms power-on delay + noise filtering ensures zero inadvertent writes during brown-out or EMI events. |
| Software Data Protection (SDP) | User-configurable lock via 3-byte command sequence (AAh/55h/A0h) to prevent accidental overwrites in production firmware. |
| Page Write Architecture | 128-byte internal latch reduces host-side timing constraints; eliminates need for external address/data latches. |
| Two-Mode Write Detection | DATA POLLING (I/O7 complement) and TOGGLE BIT (I/O6 toggling) provide flexible, software-transparent write completion signaling. |
| Industrial Temperature Range | -40°C to +85°C operation validated per AC/DC specs - suitable for motor drives, PLCs, and outdoor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15JI | Same die and timing, but in PLCC-32 package with industrial (-40°C to +85°C) rating. | Preferred for through-hole prototyping or high-vibration environments where TSOP solder joints may fatigue. | Select AT28C010-15JI when mechanical robustness or socket-based validation is required; same functional behavior as AT28C010-15TC. |
| ST M28C17-150K1 | 1 Mbit paged EEPROM with identical 150 ns read, 10 ms page write, and 5 V supply, but uses different SDP command sequence and lacks TOGGLE BIT detection. | Suitable for cost-sensitive designs where only DATA POLLING is needed and Atmel-specific firmware tools are not used. | Choose ST M28C17-150K1 only if existing toolchain supports its unique unlock sequence; no pin-to-pin compatibility with AT28C010-15TC. |
Compared with AT28C010-15TC, AT28C010-15JI offers identical electrical performance in a more mechanically stable package, while ST M28C17-150K1 provides functional equivalence with reduced feature set and incompatible software protection protocol - requiring firmware revalidation.

FAQ
What is the maximum page write size supported by the AT28C010-15TC?
The AT28C010-15TC supports page writes of 1 to 128 bytes per cycle. The device uses internal latches to capture all data within a single page (defined by A7–A16), allowing the host to stream up to 128 bytes with ≤150 µs between successive writes. This capability is confirmed in the "Page Write" section of the official datasheet and applies directly to the AT28C010-15TC variant.
Does the AT28C010-15TC require an external high-voltage supply for programming?
No, the AT28C010-15TC operates entirely from a single 5 V ±10% supply - no external 12 V or higher voltage is needed for standard byte or page writes. Only the optional device identification area (1FF80H–1FFFFH) requires 12 V ±0.5 V on A9, which is unrelated to normal AT28C010-15TC operation. All core programming functions execute at 5 V.
How does hardware write protection work on the AT28C010-15TC?
The AT28C010-15TC implements four hardware safeguards: (1) VCC sense circuitry that disables writes below ~3.8 V, (2) automatic 5 ms power-on delay before write enable, (3) write inhibition when CE is high, OE is low, or WE is high, and (4) filtering of sub-15 ns noise pulses on WE/CE. These mechanisms are intrinsic to the AT28C010-15TC silicon and require no external components.
Can the AT28C010-15TC be used as a direct replacement for the 27C512 EPROM?
Yes, the AT28C010-15TC uses JEDEC-approved byte-wide pinout and shares identical address/data/control signal assignments with the 27C512, enabling socket-level replacement. However, unlike UV-erasable EPROMs, the AT28C010-15TC supports in-system electrical erasure and does not require UV exposure - making it a true functional and physical upgrade path.
What is the difference between the 'C' and 'I' suffixes in AT28C010-15TC versus AT28C010-15TI?
The 'C' in AT28C010-15TC denotes commercial temperature range (0°C to +70°C), while 'I' in AT28C010-15TI indicates industrial range (-40°C to +85°C). Both share identical electrical specifications including 150 ns read access, 10 ms page write, and 5 V supply, but AT28C010-15TI is fully characterized and guaranteed across the wider thermal envelope - critical for deployment in harsh environments.
