Description The Atmel AT27C256R is a low-power, high-performance, 262,144-bit, one-time pro- grammable, read-only memory (OTP EPROM) organized as 32K by 8 bits. It 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 micropro- cessor systems. The Atmel scaled CMOS technology provides low active power consumption and fast pro- gramming. Power consumption is typically only 8mA in active mode and less than 10A in standby mode. The AT27C256R 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 32K byte storage capability, the AT27C256R allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. The AT27C256R 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 100s/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. 0014OEPROM10/112.

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 non-conformance. At a minimum, a 0.1F, 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 4.7F 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.
