Description The Atmel® AT27C040 is a low-power, high-performance, 4,194,304-bit, One-Time Programmable, Read-Only Memory (OTP EPROM) organized as 512K by 8 bits. The AT27C040 requires only one 5V power supply in normal Read mode operation. Any byte can be accessed in less than 70ns, eliminating the need for speed reducing wait states on high-performance microprocessor systems. The Atmel scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically 8mA in active mode and less than 10μA in standby mode. The AT27C040 is available in a choice of industry standard, JEDEC-approved, PDIP and PLCC packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. The AT27C040 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 100μs/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. 0189J–EPROM–10/2012 Pin Configurations and Pinouts 30 28 7 27 8 26 9 25 10 24 11 23 12 22 13 21 O1 O2 GND O3 O4 O5 O6 Device Power Supply 31 Output Enable 6 20 OE 29 19 Chip Enable 1 CE 32 Ground 5 18 GND A7 A6 A5 A4 A3 A2 A1 A0 O0 17 Outputs 2 O0 - O7 16 Address Inputs A12 A15 A16 VPP VCC A18 A17 A0 - A18 3 Peak to Peak Voltage 4 VPP 15 Function VCC 32-lead PDIP Top view 32-lead PLCC Top view Pin Name 14 2. 3.

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 VCC and ground terminals of the device — as close to the device as possible. 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 VCC and ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array. 4.

Rapid programming algorithm A 100μs CE 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 100μs CE pulse without verification. Then a verification/reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to ten successive 100μs pulses are applied with a verification after each pulse. If the byte fails to verify after ten pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is selected until all have been checked. VPP is then lowered to 5.0V and VCC to 5.0V. All bytes are read again and compared with the original data to determine if the device passes or fails. Figure 7-1.
