VAS 5054A Infineon 32F40F vs. 16F40F: 32F40F Faster!

I have both on 2 different vas 5054a heads, with different QC Mark labels on infineon. One vas5054a comes with 32F40F the other vas5054a comes with 16F40F.

32F40F
On-Chip Memory Modules – 2 Kbytes On-Chip Dual-Port RAM (DPRAM) – 4 Kbytes On-Chip Data SRAM (DSRAM) – 6 Kbytes On-Chip Program/Data SRAM (PSRAM) – 256 Kbytes On-Chip Program Memory (Flash Memory)

16F40F
On-Chip Memory Modules – 2 Kbytes On-Chip Dual-Port RAM (DPRAM) – 4 Kbytes On-Chip Data SRAM (DSRAM) – 2 Kbytes On-Chip Program/Data SRAM (PSRAM) – 128 Kbytes On-Chip Program Memory (Flash Memory)

16F40 should be ok. Just be carefull if it’s not 16F20, which runs at 20Mhz.

But 16F40F is slower than 32F40F.
