![]() When BYTE is at logic high, the word-wide mode is enabled, where data is read and programmed on DQ0-DQ15. ![]() DQ8-DQ14 are tri-stated during the byte-wide mode. When BYTE is at logic low, the byte-wide mode is enabled, where data is read and programmed on DQ0-DQ7 and DQ15/A-1 becomes the lowest order address that decodes between the upper and lower byte. With PonyProg and SI-Prog you can program Wafercard for SAT, eeprom within GSM, TV or CAR-RADIO. Its purpose is reading and writing every serial device. BYTE pin must be controlled at CMOS levels to meet the CMOS current specification in standby mode. PonyProg is a serial device programmer software with a user friendly GUI framework available for Windows and Linux. This pin must be set at power-up or return from deep power-down and not changed during device operation. If CE and RP are high, but not at a CMOS high level, the standby current will increase due to current flow through the CE and RP input stages.īYTE: Configures whether the device operates in byte-wide mode (x8) or word-wide mode (x16). CE high de-selects the memory device and reduces power consumption to standby levels. ![]() Addresses and data are latched on the rising edge of the WE pulse.ĬE (CHIP ENABLE): Activates the device's control logic, input buffers, decoders and sense amplifiers. WE (WRITE ENABLE): Controls writes to the command register and array blocks. OE (OUTPUT ENABLE): Enables the device's outputs through the data buffers during a read cycle.
