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
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.
