General Description
The S25FL064P is a 3.0 Volt (2.7V to 3.6V), single-power-supply flash memory device. The device consists of 128 uniform 64kB sectors with the two(Top or Bottom)64 kB sectors further split up into thirty-two 4 kB sub sectors. The S25FL064P device is fully backward compatible with the S25FL064A device.
The device accepts data written to SI(Serial Input) and outputs data on SO(Serial Output). The devices are designed to be programmed in-system with the standard system 3.0-volt Vcc supply.
The S25FL064P device adds the following high-performance features using 5 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 S, 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 /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 The memory can be programmed 1 to 256 bytes at a time, using the Page Program command. The device supports Sector Erase and Bulk Erase commands.
Each device requires only a 3.0-volt power supply (2.7V to 3.6V) for both read and write functions. Internally generated and regulated voltages are provided for the program operations. This device requires a high voltage supply to the W#/ACC pin to enable the Accelerated Programming mode.
The S25FL064P device also offers a One-Time Programmable area(OTP) of up to 128-bits (16 bytes) for permanent secure identification and an additional 490 bytes of OTP space for other use. This OTP area can be programmed or read using the OTPP or OTPR instructions.
