Preliminary
32-bit General-purpose Single-chip Microcontroller
1/39
GENERAL DESCRIPTION
This LSI incorporates PLAT
-7B, employing the CPU core ARM7TDMI, as the CPU platform and operates at
maximum 33 MHz. It contains built-in RAM and peripheral IOs such as Timer, WDT, GPIO, PWM, UART
(16550 compatible), AD converter, DMA controller and DRAM controller, etc. and can be used as a
microcontroller for configuring various systems.
