AT27C010
1. Description
The AT27C010 is a low-power, high-performance 1,048,576-bit one-time programma-
ble 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-perfor-
mance 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 one-
time programmable (OTP) plastic PDIP, PLCC, and TSOP packages. All devices fea-
ture 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 produc-
tion 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.
