S08SH|8-bit General Purpose SH MCUs

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.

Features

8-bit HCS08 Central Processor Unit (CPU)

Up to 40 MHz HCS08 CPU (20 MHz bus frequency) for 50 ns minimum instruction time
HC08 instruction set with added BGND instruction
Support for up to 32 interrupt/reset sources

Integrated Third-Generation Flash Memory and RAM

Embedded flash that is in-application reprogrammable
Fast, byte-writable programming, as fast as 20 µs/byte
Up to 100,000 write/erase cycles at typical voltage and temperature (10k minimum write/erase)
100 years typical data retention (15 years minimum)

Flexible Clock Options

Internal clock source (ICS) module containing a frequencylocked loop (FLL) controlled by internal or external reference
Precision trimming of internal reference allows typical 0.1 percent resolution and +0.5 percent to -1 percent deviation over operating temperature and voltage
Internal reference can be trimmed from 31.25 kHz to 39.065 kHz, allowing for 16 MHz to 20 MHz FLL output
Low-power oscillator module (XOSC)
- software selectable crystal or ceramic resonator range, 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz,
- 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

Serial communications interface module with option for 13-bit break capabilities and double-buffered transmit and receive
Serial peripheral interface module and I²C bus module

Integrated Analog Peripherals

Three Timer Modules

Programmable 16-bit timer/PWM modules (TPM1 and TPM2)
8-bit modulo timer module (MTIM) with 8-bit prescaler

System Protection

Watchdog computer operating properly (COP) reset with option to run from dedicated 1 kHz internal clock source or bus clock
