MC9S08SH8CTJR Description

The MC9S08SH8CTJR is an S08SH 8-bit MCU, S08 core, 8KB Flash, 40MHz, SOP 20. The S08SH family is a collection of S08 8-bit microcontrollers that provides a new low-cost option for 5-volt applications. The S08SH family provides more design options because it is pin, tool, and software compatible with the S08SG. Additionally, it offers a wide range of peripherals, including analog-to-digital converters (ADC), analog comparators, temperature sensors, serial peripheral interfaces (SPI), serial communications interface (SCI), and I2C.

MC9S08SH8CTJR Features

Peripherals

• ADC — 12-channel, 10-bit resolution, 2.5 μs conversion time, automatic compare function, temperature sensor, internal bandgap reference channel; runs in stop3

• ACMP — Analog comparator with selectable interrupt on rising, falling, or either edge of comparator output; compare option to fixed internal bandgap reference voltage; output can be optionally routed to TPM module; runs in stop3

• SCI — Full duplex non-return to zero (NRZ); LIN master extended break generation; LIN slave extended break detection; wake up on active edge

• SPI — Full-duplex or single-wire bidirectional; Double-buffered transmit and receive; Master or Slave mode; MSB-first or LSB-first shifting

• IIC — Up to 100 kbps with maximum bus loading; Multi-master operation; Programmable slave address; Interrupt driven byte-by-byte data transfer; supports broadcast mode and 10-bit addressing

• MTIM — 8-bit modulo counter with 8-bit prescaler and overflow interrupt

• TPMx — Two 2-channel timer pwm modules (TPM1, TPM2); Selectable input capture, output compare, or buffered edge- or center-aligned PWM on each channel

• RTC — (Real-time counter) 8-bit modulus counter with binary or decimal based prescaler; External clock source for precise time base, time-of-day, calendar or task scheduling functions; Free running on-chip low power oscillator (1 kHz) for cyclic wake-up without external components, runs in all MCU modes

Input/Output

• 17 general purpose I/O pins (GPIOs) and 1 output-only pin

• 8 interrupt pins with selectable polarity

• Ganged output option for PTB[5:2] and PTC[3:0]; allows single write to change state of multiple pins

• Hysteresis and configurable pull up device on all input pins; Configurable slew rate and drive strength on all output pins.

Package Options

• 24-QFN, 20-TSSOP, 20-SOIC, 20-PDIP, 16-TSSOP, 8-SOIC

8-Bit HCS08 Central Processor Unit (CPU)

• 40-MHz HCS08 CPU (central processor unit)

• HC08 instruction set with added BGND instruction

• Support for up to 32 interrupt/reset sources

On-Chip Memory

• FLASH read/program/erase over full operating voltage and temperature

• Random-access memory (RAM)

Power-Saving Modes

• Two very low power stop modes

• Reduced power wait mode

• Very low power real time interrupt for use in run, wait, and stop

Clock Source Options

• Oscillator (XOSC) — Loop-control Pierce oscillator; Crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz

• Internal Clock Source (ICS) — Internal clock source module containing a frequency-locked loop (FLL) controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supports bus frequencies from 2 MHz to 20 MHz.

System Protection

• Watchdog computer operating properly (COP) reset with opti/n to run from dedicated 1-kHz internal clock source or bus clock

• Low-voltage detection with reset or interrupt; selectable trip points

• Illegal opcode detection with reset

• Illegal address detection with reset

• FLASH block protect

Development Support

• Single-wire background debug interface

• Breakpoint capability to allow single breakpoint setting during in-circuit debugging (pluss two more breakpoints in on-chip debug module)

• On-chip, in-circuit emulation (ICE) debug module containing two comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow address and event-only data. Debug module supports both tag and force breakpoints.
