2.1
It seemed not feasible to put a 16-bit microcontroller into a tiny package such as the
TQFP-64 when the Infineon C166 Family was created. In the meantime, however,
several improvements were added to the architecture which, when combined, allow
high-performance operation of a 16-bit microcontroller in a 64-pin package.
The combination of the following features was the basis for the realization of a compact
microcontroller such as the C164CM:
• Single Chip Mode without reset configuration via PORT0 removes the need for
• Serial Interfaces on PORT0 allow the removal of Port 3, while retaining the
• Modified multiplexed bus mode with 8-bit data and 11-bit address enables the
• CAN interface on Port 8 allows the removal of Port 4. This reduces the pin-count.
• Introduction of Port 20 adds IO functionality to several formerly dedicated pins which
• On-chip Program Memory (OTP, ROM) supports development and volume
Cutting features only where required, moving vital functions to the remaining pins,
adding new features such as configuration via software, maintaining the basic
architecture (on-chip PLL, 16-bit CPU, PEC, interrupt controller, memory concept),
keeping powerful industry-standard peripheral modules such as CAPCOM6 and CAN,
resulted in a compact member of Infineon’s C166 Family of 16-bit microcontrollers which
fits to a board space of merely 1.44 cm
