Atmel AT27C010
Description
The Atmel® 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. Thedevice
requires only one 5V power supply in normal read mode operation. Any byte can be
accessed in less than 45ns, eliminating the need for speed reducing WAIT states on highperformance microprocessor systems.
In read mode, the AT27C010 typically consumes only 8mA. Standby mode supply current
is typically less than 10µA.
The AT27C010 is available in a choice of industry standard, JEDEC approved, one-time programmable (OTP) PDIP and PLCC 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.
The 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.
