The 32-bit modular microcontroller combines a CPU32 core with system integration, general-purpose timer, and queued serial modules connected through an intermodule bus. The clock system can synthesize an internal clock from a 32.768 kHz reference or use an external clock input, with a maximum system clock speed of 20.97 MHz. Serial resources include an enhanced SCI UART and a QSPI with 80-byte RAM and up to 16 automatic transfers. Timer resources include two 16-bit free-running counters, input capture, output compare, pulse accumulation, and two PWM outputs. QFP package options include 132-pin and 144-pin configurations.
