General Description
The S25FL032P is a 3.0 V (2.7 V to 3.6 V), single-power-supply Flash memory device. The device consists of 64 uniform 64-KB sectors with the two (top or bottom) 64-KB sectors further split up into thirty-two 4-KB sub sectors. The S25FL032P device is fully backward compatible with the S25FL032A device.
The device accepts data written to Serial Input (SI) and outputs data on Serial Output (SO). The devices are designed to be programmed in-system with the standard system 3.0-V VCC supply.
The S25FL032P device adds the following high-performance features using five new instructions:
■ Dual Output Read using both SI and SO pins as output pins at a clock rate of up to 80 MHz
■ Quad Output Read using SI, SO, W#/ACC, and HOLD# pins as output pins at a clock
rate of up to 80 MHz
■ Dual I/O High Performance Read using both SI and SO pins as input and output pins at a clock
rate of up to 80 MHz
■ Quad I/O High Performance Read using SI, SO, W#/ACC, and HOLD# pins as input and output
pins at a clock rate of up to 80 MHz
■ Quad Page Programming using SI, SO, W#/ACC, and HOLD# pins as input pins to program data
at a clock rate of up to 80 MHz
