1. Description

The AT27C010 is a low-power, high-performance 1,048,576-bit one-time programmable

read-only memory (OTP EPROM) organized as 128K by 8 bits. They require only

one 5V power supply in normal read mode operation. Any byte can be accessed in

less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance

microprocessor systems.

In read mode, the AT27C010 typically consumes only 8 mA. Standby mode supply

current is typically less than 10 μA.

The AT27C010 is available in a choice of industry-standard JEDEC-approved onetime

programmable (OTP) plastic PDIP, PLCC, and TSOP packages. All devices feature

two line control (CE, OE) to give designers the flexibility to prevent bus

contention.

With 128K byte storage capability, the AT27C010 allows firmware to be stored reliably

and to be accessed by the system without the delays of mass storage media.

Atmel’s AT27C010 has additional features to ensure high quality and efficient production

use. The Rapid Programming Algorithm reduces the time required to program the

part and guarantees reliable programming. Programming time is typically only

100 μs/byte. The Integrated Product Identification Code electronically identifies the

device and manufacturer. This feature is used by industry-standard programming

equipment to select the proper programming algorithms and voltages.
