NXP MC9S08SH8MTJ

S0840MHz8KB（8K x 8）

Overview

The MC9S08SH8MTJ is a 8-bit General-purpose Microcontroller based on enhanced HCS08 CPU (20MHz bus) with CISC architecture operates at a maximum frequency of 40MHz. The device incorporates 8kB internal flash, 0.512kB internal RAM, an analog comparator, 12-channel 10-bit A/D converter and 17 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module to operate at up to 100kbps, one serial peripheral interface modules (SPI) and one serial communications interface (SCI) module.

Features

• 8-bit HCS08 Central Processor Unit (CPU)

      Support for up to 32 interrupt/reset sources

      HC08 instruction set with added BGND instruction

      Up to 40 MHz HCS08 CPU (20 MHz bus frequency) for 50 ns minimum instruction time

• Integrated Third-Generation Flash Memory and RAM

      100 years typical data retention (15 years minimum)

      Embedded flash that is in-application reprogrammable

      Extremely 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)

• Flexible Clock Options

      Internal clock source (ICS) module containing a frequency locked loop (FLL) controlled by internal or external reference

      The internal reference can be trimmed from 31.25 kHz to 39.065 kHz, allowing for 16 MHz to 20 MHz FLL output

      Precision trimming of internal reference allows typical 0.1 percent resolution and +0.5 percent to -1 percent deviation over operating temperature and            voltage

• Input/Output

      One Output-Only Line

      Up to 23 bidirectional lines

      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)

      Safely drives multiple outputs

      Allows single write to change state of multiple pins

      Drives up to 80 mA without risk of run away code shorting

      Provides option to tie multiple pins from different ports to same control registers

• Multiple Serial Communication Options

      Serial peripheral interface module and I2C bus module

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

• 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

      Low-voltage detection with reset or interrupt

      Illegal opcode detection with reset
