Product details
Overview
AT28C010-15TI 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 industrial temperature range (–40°C to +85°C), enabling use in embedded control firmware storage and configuration memory for industrial PLCs.
For engineers reviewing the AT28C010-15TI datasheet, AT28C010-15TI pinout, AT28C010-15TI application, or AT28C010-15TI equivalent, key selection criteria include verified page-write endurance (10⁴ cycles), DATA polling and TOGGLE BIT write completion detection, hardware/software data protection, and PLCC-32 package compatibility with legacy board layouts.
Technical Context
The AT28C010-15TI implements a paged architecture with a 128-byte internal page register, allowing up to 128 bytes to be latched and written in a single internal programming period. Address latching occurs on the falling edge of CE or WE, and data latching on the first rising edge of either control signal.
Write completion is confirmed via DATA polling (I/O7 complement behavior) or TOGGLE BIT (I/O6 toggling), both operable at any point during the write cycle. Hardware protection includes VCC sense (<3.8 V inhibit), 5 ms power-on delay, noise filtering (<15 ns pulse rejection), and CE/OE/WE state-based write inhibition.

Pinout & Package
AT28C010-15TI is packaged in a 32-lead Plastic J-leaded Chip Carrier (PLCC), JEDEC MS-016 AE compliant, with pin 1 marked and designated as "Don't Connect" (DC). The package is lead-free compatible and designed for surface-mount reflow assembly.
| 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 writes |
| I/O0–I/O7 | Bidirectional Data Bus | Byte-wide data path; I/O7 used for DATA polling, I/O6 for TOGGLE BIT status indication |
| CE | Chip Enable | Active-low chip select; must be low with OE low and WE high for read; write inhibited if high |
| OE | Output Enable | Active-low output control; high-Z when high, enabling bus sharing without external transceivers |
| WE | Write Enable | Active-low write strobe; falling edge latches address; rising edge latches data in byte/page mode |
| NC / DC | No Connect / Don't Connect | Pin 1 (PLCC) is DC per datasheet; other NC pins must remain unconnected to avoid latch-up or timing violation |
| VCC, GND | Power Supply | Single 5V supply with <200 µA CMOS standby current - reduces system power budget in sleep modes |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Page Write | 128-byte internal latching eliminates host CPU wait states during multi-byte writes |
| DATA Polling & TOGGLE BIT | Dual asynchronous write-complete detection avoids fixed timeout delays and improves real-time responsiveness |
| Hardware + Software Data Protection | VCC-sense, noise filtering, and 3-byte SDP command prevent corruption during brown-out or EMI events |
| JEDEC Byte-wide Pinout | Direct drop-in replacement for industry-standard EPROMs and SRAMs in existing PCB footprints |
| Industrial Temperature Range | Validated operation from –40°C to +85°C supports deployment in harsh factory-floor environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15PI | Same die and timing specs; uses 32-lead PDIP (32P6) instead of PLCC (32J) | Through-hole mounting required; incompatible with surface-mount PLCC footprint | Select only if legacy through-hole assembly is mandated and board redesign is not feasible |
| AT28C010-15TC | Same die and timing specs; uses 32-lead TSOP (32T) package with 0.5 mm pitch | Smaller footprint and lower profile; requires fine-pitch reflow process and different pad layout | Choose for space-constrained designs where height and area are critical, and TSOP assembly capability exists |
Compared with AT28C010-15TI, the AT28C010-15PI offers identical electrical performance but demands through-hole assembly and board-level mechanical redesign, while the AT28C010-15TC provides identical functionality in a smaller surface-mount package requiring updated stencil and placement tooling - neither is pin-compatible with the PLCC variant.

FAQ
What is the maximum page write size supported by the AT28C010-15TI?
The AT28C010-15TI supports a maximum page write size of 128 bytes. This is enabled by its internal 128-byte page register, which latches address and data simultaneously. Each byte in a page write must be loaded within 150 µs of the previous one (tBLC), and all addresses must reside on the same page defined by A7–A16. The AT28C010-15TI does not support partial-page or cross-page writes in a single operation.
Does the AT28C010-15TI require a 12V programming voltage?
No, the AT28C010-15TI operates exclusively from a single 5V ±10% supply for both read and write operations. A 12V supply is required only for optional device identification memory (128 bytes at 1FF80H–1FFFFH), which is separate from main array programming. Standard byte and page writes for the AT28C010-15TI use only 5V - no high-voltage pump or external charge circuitry is needed.
How is write completion detected on the AT28C010-15TI?
The AT28C010-15TI provides two independent, asynchronous methods: DATA polling (monitoring I/O7 for complement-to-data behavior) and TOGGLE BIT (observing I/O6 toggling until it stabilizes). Both methods can be initiated at any time during the write cycle and eliminate the need for fixed timeout waits. For the AT28C010-15TI, these mechanisms are fully functional across its industrial temperature range and require no additional hardware.
Is software data protection (SDP) enabled by default on the AT28C010-15TI?
No, the AT28C010-15TI ships with software data protection disabled. SDP must be explicitly enabled by issuing a three-byte command sequence (AAh to 5555h, 55h to 2AAAh, A0h to 5555h). Once enabled, all subsequent writes require repeating this sequence before data. Power cycling does not disable SDP - it remains active until the dedicated disable command (80h/5555h → 55h/2AAAh → 20h/5555h) is executed on the AT28C010-15TI.
What package type is used for the AT28C010-15TI?
The AT28C010-15TI uses a 32-lead Plastic J-leaded Chip Carrier (PLCC), designated as package code "32J" per Atmel's ordering guide. Pin 1 is marked and defined as "Don't Connect" (DC). This surface-mount package complies with JEDEC standard MS-016 AE and is distinct from the PDIP (32P6) and TSOP (32T) variants offered for the same AT28C010-15 speed grade.
