Hi Sui Peng,
PSoC3/5 comes in variants having 25, 38 and 62 GPIOs.
How many pins would your application require?
62 GPIOs and 8 SIOs. How many pins your appication need ? Also note that all GPIOs can act as both analog and digital, this gives lot of flexbility.
Dear dasq & pvkv Thanks for your response! My application need GPIOs(SIOs) approximately . (The user custom analog module:18 GPIOs;user custom digital module:16 GPIOs;LCD Drive module:13 GPIOs;Capsense module:more than 32 GPIOs;USB : 2 GPIOs;I2C :2 GPIOs;External Crystal:2 GPIOs;Debug interface:3 or 5 GPIOs;etc.... B/R Sui Peng
What are the Analog pins/Capsense pins for? Can you expatiate?
