Version: **

 

Question:

What are the differences between PSoC® 4100S Plus and PSoC 4100S family of devices?

 

Answer:

The PSoC 4100S Plus family of devices offer larger flash memory, more peripherals, and more I/Os when compared to the PSoC 4100S devices. See Table 1-1 for the detailed list of differences.

On CapSense®, the PSoC 4100S Plus family of devices support the simultaneous use of external capacitors, CMOD, CTANK, CINTA, and CINTB. See AN85951, PSoC 4 and PSoC Analog Coprocessor CapSense Design Guide for pins that support external capacitor connection. A new IDAC gain of 1.2 uA/bit is added to the CapSense hardware in PSoC 4100S Plus device. The CapSense hardware in the PSoC 4100S Plus family of devices support IDAC gains of 37.5 nA, 300 nA, 1.2 uA, and 2.4 uA. It also supports external 4- to 33-MHz crystal oscillator (ECO). A high-frequency clock (HFCLK) of up to 48 MHz, selected from IMO, ECO, external clock, or PLL can also be used.
