Applications
PIC18F1320-I/SS targets embedded control applications such as smart motor controllers, portable medical monitors, and consumer device firmware that need PIC18 performance in a compact 20-pin SSOP footprint. Its 256 bytes of on-chip EEPROM allows persistent storage of calibration data, user settings, or event logs without external memory components. The combination of 40 MHz throughput, a multi-channel ADC, and standard serial interfaces makes it effective for data logging instruments, keypad interfaces, and wireless sensor node controllers.

Frequently Asked Questions
How does PIC18F1320-I/SS's 40 MHz clock speed compare to the PIC16 family, and when does that extra throughput matter?
PIC18F1320-I/SS runs at up to 40 MHz versus the 20 MHz maximum common in PIC16 devices, doubling available MIPS to 10 MIPS. This headroom is meaningful for algorithms such as software UART at 115200 baud, PID motor control at 10 kHz update rates, or stepper pulse generation requiring tight timing resolution below 1 µs.
With 256 bytes of on-chip EEPROM, what kind of data can PIC18F1320-I/SS store without requiring an external I2C memory?
256 bytes of EEPROM on PIC18F1320-I/SS comfortably stores up to 64 four-byte floating-point calibration constants, 128 two-byte sensor offsets, or a 256-entry event code log. This eliminates the need for an external AT24Cxx EEPROM, saving one I2C device, 2 resistors, and approximately 4 mm² of PCB space per board.
Is the SSOP-20 package of PIC18F1320-I/SS suitable for hand soldering during prototyping, and what pitch do the pads use?
The SSOP-20 package uses a 0.65 mm lead pitch, which is manageable with a fine-tip soldering iron and solder wick for prototype rework, though more challenging than the 2.54 mm pitch of a PDIP package. Most designers use hot-air rework stations or PCB reflow for volume assembly, with the 0.65 mm pitch enabling a 10-pin-per-side footprint in roughly 7.8 mm x 5.3 mm total package area.
