其他系列 40MHz 闪存：16K@x8bit RAM：1KB
Overview
The S08SH family is a series of S08 8-bit microcontrollers that offer a new low-end option for applications in the 5-volt range. The S08SH family is pin, tool and software compatible with S08SG, offering greater design flexibility. It also has wide peripheral offering with serial communications interface SCI, serial peripheral interface SPI, I²C, analog-to-digital converter ADC, analog comparator and temperature sensor.

* supports external clock source input up to 40 MHz
### Input/Output
* Up to 23 bidirectional lines
* One Output-Only Line
* Outputs 10 mA each; 60 mA max for package
* Software selectable pull-ups on ports when used as input
* internal pull-up on reset and interrupt request IRQ pin
* Software selectable slew rate control and drive strength on ports when used as output
* 8-pin keyboard interrupt module with software selectable polarity on edge or edge/level modes
### Ganged Output Option for PTB 5:2 and PTC 3:0
* Allows single write to change state of multiple pins
* Drives up to 80 mA without risk of runaway code shorting
* Provides option to tie multiple pins from different ports to same control registers
* Safely drives multiple outputs
### Multiple Serial Communication Options
