Besides the innovative SCU, R8C/33T MCUs incorporate an R8C 16-bit CPU core, a data transfer controller (DTC) and a wide range of peripheral functions, including multiple serial interfaces, 8- and 16-bit timers, and up to 12 channels of analog-to-digital conversion, as well as high-current ports for direct LED control.
Furthermore, these microcontrollers provide an extensive set of other peripheral functions, including data flash for non-volatile data storage and data transfer controller and DMAC to reduce the CPU load.
The new devices integrate a number of advanced features such as a data transfer controller (DTC) and data flash memory with a background operation (BGO) function, which are already available in many R8C devices today.
It includes a direct memory access (DMA) controller, data transfer controller (DTC), 6-channel 16-bit timer pulse unit (TPU), programmable pulse generator (PPG) and a watchdog timer (WDT).
The controllers also have a data transfer controller (8-bit external bus), interrupt controller, user break controller, and clock-pulse generator with built-in multiplication phase locked loop.
High-speed clock-synchronous serial data communication at over one Mbit/sec can easily be achieved by using the device's data transfer controller (DTC) and direct memory access controller (DMAC).
5 volts (V) -- Four 8-bit timers, six 16-bit timers and two watchdog timers -- 85-channel data transfer controller -- Eight-channel 10-bit A/D and two-channel 8-bit D/A -- 32KHz built-in subclock generator to minimize power consumption -- Four serial communication interface channels, universal asynchronous receiver/transmitter (UART) or clocked synchronous mode -0- The H8S/2238 device will be followed in year 2000 by a series of derivative H8S baseband microcontrollers to include serial communication speed enhancements and USB connectivity.
