GENERAL DESCRIPTION
DS-TMU3132MS_E
USB Full Speed Controller
The TMU3132MS is a 2T RISC tailored to the USB 2.0 full speed general purpose IC. It
contains 4K * 14 Mask ROM. The Internal RC Oscillator is 48 MHz +/- 0.25% for USB mode
and 12 MHz clock output for the RF 2.4G module. The USB DMA channel allows data transfer
between USB RAM with SPI interface which supports mode 0/1/2/3 master up to 6 Mbps clock
rate. The TMU3132MS also supports suspend mode, wake-up and watchdog timer. The data
memory is internal 160 bytes of RAM in F-plane and two 64 bytes in R-plane. The
TMU3132MS USB MCU is suited for USB mouse and wireless 2.4G dongle device.
