Description The Atmel® AT27C010 is a low-power, high-performance 1,048,576-bit, one-time pro- grammable, 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 high- performance 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 pro- grammable (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 guar- antees 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 pro- gramming algorithms and voltages. 0321N–EPROM–4/11

System considerations Switching between active and standby conditions via the chip enable pin may produce transient voltage excursions. Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device nonconformance. At a minimum, a 0.1µF, high-frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the V and ground terminals of the device, as close to the device as possible. CC Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7µF bulk electrolytic capacitor should be utilized, again connected between the V and ground terminals. This capacitor should be positioned as CC close as possible to the point where the power supply is connected to the array. Figure 3-1. Block diagram Atmel AT27C010 2 0321N–EPROM–4/11

6. Rapid programming algorithm A 100µs PGM pulse width is used to program. The address is set to the first location. V is raised to 6.5V and V is raised CC PP to 13.0V. Each address is first programmed with one 100µs 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 100µs pulses are applied with a verification after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is selected until all have been checked. V is then lowered to 5.0V and V to 5.0V. All bytes are read again and compared with the original data to PP CC determine if the device passes or fails. Figure 6-1.
