Description

The AT27C010(L) is a low-power, high-performance 1,048,576-bit one-time program-

mable 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-per-

formance microprocessor systems.

Two power versions are offered. In read mode, the AT27C010 typically consumes 25

mA while the AT27C010L requires only 8 mA. Standby mode supply current for both

parts is typically less than 10 µA.

The AT27C010(L) in available in a choice of industry standard JEDEC-approved one-time 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(L) allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s 27C010(L) have additional features to ensure high quality and efficient production use.

AT27C010(L) AC Waveforms for Read Operation(1) Notes: 1. Timing measurement reference level is 1.5V for -45 and -55 devices. Input AC drive levels are VIL = 0.0V and VIH = 3.0V. Timing measurement reference levels for all other speed grades are V OL = 0.8V and VOH = 2.0V. Input AC drive levels are VIL = 0.45V and VIH = 2.4V. 2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE. 3. OE may be delayed up to tACC - tOE after the address is valid without impact on tACC.

Programming Waveforms(1) Notes: 1. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH. 2. tOE and tDFP are characteristics of the device but must be accommodated by the programmer. 3. When programming the AT27C010(L) at 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage transients. DC Programming Characteristics TA = 25 ± 5°C, VCC = 6.5 ± 0.25V, VPP = 13.0 ± 0.

Rapid Programming Algorithm A 100 µs PGM pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 100 µs PGM pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are applied with a verification 8 AT27C010(L) after each pulse.
