Detailed Description

1 Mbit parallel EEPROM, organized as 128K x 8. 5 V supply (4.5–5.5 V). 150 ns read access time. Byte/page-write capable with typical 10 ms write cycle. Industrial temperature range -40°C to +85°C. Surface-mount 32-PLCC with J-leads. RoHS non-compliant device.

Key Features

Non-volatile EEPROM technology, data retained without power

128K x 8 organization for simple byte addressing

Parallel bus interface for easy MCU/FPGA/ASIC connections

Read access time 150 ns for quick data retrieval

5 V-only operation, no special programming voltages

Byte and page write operations, typical 10 ms write cycle

Industrial temperature performance (-40°C to +85°C)

Standard control signals CE, OE, WE for straightforward bus timing

Software data protection features commonly available in this family

Tube packaging for safe handling and assembly

Key Advantages

Drop-in friendly for legacy 5 V parallel memory designs

Simple interface reduces firmware and hardware complexity

Stable long-term data retention typical of EEPROM technology

Supports frequent small updates compared to one-time or block-oriented memories

Mature, well-documented product line minimizes design risk

Industrial-grade reliability over extended temperature ranges

Packaging

Type: Device package 32-PLCC with J-leads, supplier device package 32-PLCC (13.97 x 11.43 mm)

Material: Molded plastic PLCC body, tin/lead J-leads (RoHS non-compliant lead finish)

Size: Approx. 13.97 mm x 11.43 mm body, 32-pin footprint

Pin configuration: 32-pin PLCC J-lead. Typical signals include A0–A16 (address), D0–D7 (data), CE, OE, WE, VCC (5 V), GND, and NC pins as defined in the datasheet. Verify exact pinout before design.

Thermal characteristics: Industrial temperature range -40°C to +85°C (TC). Standard PLCC thermal performance; ensure adequate airflow and keep within maximum power dissipation limits specified in the datasheet.

Electrical properties: Supply 4.5–5.5 V, 150 ns access time, parallel interface, typical 10 ms byte/page write cycle. TTL/CMOS-compatible I/O per family norms. Refer to datasheet for current consumption and precise timing.

Lifecycle

Status: This is a mature Microchip Technology EEPROM family. Availability may vary by package and speed grade; some variants can shift to NRND/EOL over time. The listed device is RoHS non-compliant, which can affect long-term supply in certain regions.

Suggested equivalents or alternatives (verify compatibility, timing, and temperature ratings in datasheets):

- AT28C010E-12JI (same family, faster 120 ns, industrial temp, PLCC)

- AT28C010-15JI (earlier non-E variant, 150 ns, industrial temp, PLCC)

- AT28C010-12JI (non-E variant, 120 ns, industrial temp, PLCC)

- AT28C010E in other packages (e.g., PDIP 32) for through-hole designs

- AT29C010A-xxJI (1 Mbit parallel Flash, 5 V; not EEPROM, different erase/write behavior)

- AT28BV010 family (low-voltage variants; check VCC range and interface differences)
