Detailed Description

AM27C1024-150JC is a 1 Mbit (128K x 8) CMOS UV-erasable EPROM designed for 5 V read operation and 12.5 V programming.

150 ns access time for fast reads.

Nonvolatile memory with quartz window for UV erasure and full reprogramming.

Suitable for legacy systems, service, and long-term maintenance.

Main Category: Integrated Circuits (ICs)

Small Classification: Specialized ICs

Package / Case: 916 (supplier catalog code)

Data Code: 94+ (lot/date code range)

Quantity available: 2862 units in Y-IC stock

Key Features

128K x 8 organization (1 Mbit EPROM)

150 ns read access time

5 V-only read operation

UV-erasable via quartz window; reprogrammable using 12.5 V VPP

TTL-compatible I/O

Low-power CMOS process

Tri-state outputs for bus interfacing

Standard 32-pin EPROM pinout for A0–A16, DQ0–DQ7, CE, OE, PGM/VPP, VCC, VSS

Key Advantages

Reliable nonvolatile storage for firmware and boot code

Fully erasable and reusable, ideal for development and maintenance of legacy hardware

Wide industry compatibility due to standard EPROM pinout and timing

Long-term retention when properly stored

Stable supply from Y-IC with tested, ESD-safe handling

Packaging

Type: UV-erasable EPROM in ceramic carrier with quartz window (JC suffix commonly denotes J-leaded ceramic chip carrier)

Material: Ceramic body with glass/quartz window; J-leaded metal pins

Size: Standard 32-lead JLCC/PLCC footprint used for EPROM packages (consult datasheet for exact outline)

Pin configuration: 32 pins including

- Address: A0–A16

- Data: DQ0–DQ7

- Control: CE (chip enable), OE (output enable), PGM/VPP (program/voltage pin)

- Power: VCC, VSS

Thermal characteristics (typical for commercial EPROM variants):

- Operating temperature: 0°C to +70°C (commercial grade; other grades may exist)

- Storage temperature: -65°C to +125°C

- For detailed thermal resistance, refer to the datasheet

Electrical properties (typical):

- VCC: 5.0 V nominal (±10%)

- VPP (program): 12.5 V nominal

- Access time: 150 ns

- TTL-level inputs/outputs, tri-state capability

- Low standby current; modest active read current (see datasheet for exact limits)

Package / Case code: 916 (per supplier listing)

Shipping form: Usually trays or ESD-safe packaging appropriate for ceramic JLCC/PLCC; contact Y-IC for the exact packing of current lot

Date code: 94+ lot range available

Lifecycle

Status: Legacy/obsolete class. Many EPROMs of this generation are discontinued or limited in new production.

Availability: Y-IC maintains inventory and can source from verified stocks.

Equivalent or alternative models (verify pinout and programming algorithms before substitution):

- STMicroelectronics M27C1024 series (e.g., M27C1024-xxK/M27C1024-xxC)

- Microchip/Atmel AT27C1024 series (note: some are OTP; UV-window variants exist)

- Macronix MX27C1024 series

- Winbond W27C1024 series

- Hynix HY27C1024 series

- Fujitsu MBM27C1024 series

- 27C010 family from various vendors (e.g., ST M27C010, TI TMS27C010, Microchip AT27C010) often shares the same 128K x 8 organization and similar pinout; confirm compatibility
