Product details
Overview
AT28C010E-15TI from Microchip Technology (formerly 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 industrial temperature range (–40°C to +85°C). It supports hardware/software data protection, DATA polling, and toggle-bit write completion detection for embedded firmware storage in microcontroller systems.
For engineers reviewing the AT28C010E-15TI datasheet, AT28C010E-15TI pinout, AT28C010E-15TI application, or AT28C010E-15TI equivalent, this device serves as a drop-in replacement for legacy parallel EEPROMs requiring reliable nonvolatile storage with fast read performance, page-write efficiency, and robust write-protection in industrial control, telecom, and instrumentation designs.
Technical Context
The AT28C010E-15TI implements a CMOS-based paged architecture with a 128-byte internal page register, enabling simultaneous latching of up to 128 bytes before autonomous internal programming. Its dual-line chip enable (CE) and output enable (OE) control allows SRAM-like read/write timing without external logic.
It features VCC-sense write inhibition below 3.8 V, 5 ms power-on delay, noise-filtered WE/CE inputs (<15 ns pulse rejection), and optional software data protection (SDP) activated via a three-byte command sequence at addresses 5555H/2AAAH/5555H. Device identification space (128 bytes at 1FF80H–1FFFFH) is accessible with A9 = 12 V ± 0.5 V.

Pinout & Package
AT28C010E-15TI is packaged in a 32-lead Plastic J-leaded Chip Carrier (PLCC), JEDEC MS-016 AE compliant, with pin 1 marked by index notch and designated "DON'T CONNECT" (DC) per datasheet note. Pin 1 is not electrically connected and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 131,072-word addressing; A7–A16 define page boundaries for 128-byte page writes |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS/TTL-compatible 8-bit data path; carries latched write data and asserted read data; supports DATA polling on I/O7 and toggle-bit detection on I/O6 |
| CE | Chip Enable | Active-low primary selection signal; inhibits all operations when high; required low with OE low for read, or with WE low for write |
| OE | Output Enable | Active-low output control; places I/O pins in high-impedance state when high; must be high during write cycles |
| WE | Write Enable | Active-low write strobe; falling edge latches address/data; initiates byte or page write; hardware write inhibit active if held high |
| VCC | Power Supply | +5 V ± 10% supply input; powers core logic and memory array; includes internal VCC-sense circuitry for write safety |
| GND | Ground Reference | Signal and power return; decoupling capacitor required within 10 mm of VCC/GND pins per layout guidelines |
| NC / DC | No Connect / Don't Connect | Pin 1 (PLCC) is physically present but internally unconnected - must float, not tied to any net |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Byte-Wide Pinout | Direct drop-in compatibility with industry-standard 28-pin and 32-pin parallel EEPROM footprints, simplifying board reuse |
| 128-Byte Page Register | Reduces system bus occupancy during multi-byte writes - address/data bus freed after initial latch for concurrent operations |
| DATA Polling & Toggle Bit | Hardware-supported write completion signaling via I/O7 complement or I/O6 toggling - eliminates need for fixed delays or external timers |
| Software Data Protection (SDP) | User-configurable 3-byte command lockout prevents accidental writes during power transitions or firmware updates |
| 12 V Device ID Space | Dedicated 128-byte EEPROM region (1FF80H–1FFFFH) accessible at 12 V for serialization, calibration data, or firmware version tracking |
| VCC-Sense Write Inhibit | Automatic disable of write functionality below 3.8 V - prevents corruption during brown-out or power ramp-up |
Applications
| Industrial PLC Firmware Storage | Telecom Line Card Configuration |
|---|---|
Use Scenario: Storing firmware images and configuration parameters in programmable logic controllers operating continuously in factory environments with wide ambient temperature swings. IC Role / Device Role / Timing Role: Nonvolatile program memory holding boot code and runtime configuration; accessed via 8-bit parallel bus synchronized to microcontroller clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST M28W640ECB90N6 | 64 Mbit density, 90 ns access, 3.3 V only, no SDP, different pinout (not JEDEC byte-wide) | Higher density for firmware partitioning; requires level-shifting and board redesign | Choose only when migrating to 3.3 V systems and needing >1 Mbit capacity |
| ON Semiconductor CAT28C010WI-15 | Same 1 Mbit/150 ns spec, identical JEDEC pinout, but rated for 10K endurance (non-'E') and 200 µA standby | Lower endurance limits field reprogramming frequency; otherwise pin- and function-compatible | Select for cost-sensitive commercial applications where <1K lifetime writes are expected |
Compared with ST M28W640ECB90N6 and CAT28C010WI-15, the AT28C010E-15TI uniquely combines industrial temperature rating, 100K endurance, JEDEC-compliant pinout, and integrated software/hardware write protection - making it the optimal choice for long-lifecycle, field-upgradable industrial and medical systems requiring proven reliability without board-level changes.

FAQ
What is the endurance rating of the AT28C010E-15TI?
The AT28C010E-15TI is the high-endurance variant of the AT28C010, rated for 100,000 write/erase cycles - confirmed by Atmel's datasheet specification table and marked by the 'E' suffix in the part number. This exceeds the standard 10,000-cycle version and supports frequent firmware updates in deployed industrial equipment. The AT28C010E-15TI maintains full compatibility with all timing, voltage, and interface specifications of the base AT28C010.
Does the AT28C010E-15TI support both byte and page write operations?
Yes, the AT28C010E-15TI supports both byte and page write modes. A byte write initiates a single-location programming cycle, while a page write latches up to 128 bytes (within the same A7–A16 page boundary) and executes them internally in one 10 ms maximum operation. The AT28C010E-15TI uses the same WE/CE timing and address latching mechanism for both modes, with tBLC (byte load cycle) limiting successive byte writes to ≤150 µs intervals during page load.
How does hardware write protection work on the AT28C010E-15TI?
The AT28C010E-15TI implements four hardware write protection mechanisms: (1) VCC sense disables writes below ~3.8 V; (2) 5 ms power-on delay prevents writes until supply stabilizes; (3) write inhibit occurs if OE is low, CE is high, or WE is high; and (4) noise filtering rejects sub-15 ns pulses on WE/CE. These operate independently of software data protection and are always active. The AT28C010E-15TI relies on these features to prevent corruption during brown-out or ESD events.
Can the AT28C010E-15TI be used with a 3.3 V microcontroller interface?
No - the AT28C010E-15TI requires a 5 V ± 10% supply and is specified only for CMOS/TTL-compatible 5 V input thresholds (VIL = 0.8 V, VIH = 2.0 V). Direct connection to a 3.3 V microcontroller risks violating VIH minimum and may cause unreliable reads/writes. Level translation or voltage translation buffers are required. The AT28C010E-15TI is not 3.3 V tolerant, and its internal logic and memory array are optimized exclusively for 5 V operation.
What package type is used for the AT28C010E-15TI?
The AT28C010E-15TI uses a 32-lead Plastic J-leaded Chip Carrier (PLCC) package, identified as "32J" in Atmel's ordering guide. Pin 1 is marked by an index notch and is designated "DON'T CONNECT" (DC) - it is internally unconnected and must remain floating on the PCB. This PLCC variant supports industrial temperature operation (–40°C to +85°C) and matches JEDEC MS-016 AE mechanical dimensions.
