Iaw 5sf9 Pinout [portable]

To access the internal memory (Flash or EEPROM) for cloning services or repair, specific "special mode" pins are often required:

For bench-top operations like reading or writing data, the following connections are standard across most 5SF9 variants: iaw 5sf9 pinout

| Pin Number | Pin Name | Function | | --- | --- | --- | | 1-4 | VDD, VSS, NC, NC | Power supply, ground, and no-connect pins | | 5-12 | Port A (PA0-PA7) | General-purpose I/O pins | | 13-20 | Port B (PB0-PB7) | General-purpose I/O pins | | 21-28 | Port C (PC0-PC7) | General-purpose I/O pins | | 29-36 | SPI (SCK, MOSI, MISO, CS) | Serial peripheral interface pins | | 37-44 | I2C (SCL, SDA) | Inter-integrated circuit pins | | 45-52 | UART (TX, RX) | Universal asynchronous receiver-transmitter pins | | 53-60 | Timer/Counter (T0-T7) | Timer/counter pins | | 61-64 | Interrupt (IRQ, FIQ) | Interrupt pins | To access the internal memory (Flash or EEPROM)
