MCU 8Bit S08 S08 CISC 8KB Flash 2.5V/3.3V 16Pin TSSOP Rail
Features
• 8-Bit HCS08 Central Processor Unit CPU
– Up to 20 MHz CPU at 3.6 V to 1.8 V across temperature range of –40 °C to 85 °C
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
• On-Chip Memory
– Up to 8 KB flash memory read/program/erase over full operating voltage and temperature
– Up to 512 bytes random-access memory RAM
– Security circuitry to prevent unauthorized access to RAM and flash contents
• Power-Saving Modes
– Two very low power stop modes
– Peripheral clock enable register can disable clocks to unused modules, thereby reducing currents
– Low power run
– Low power wait
– 6 μs typical wakeup time from stop3 mode
– Typical stop current of 250 nA at 3 V, 25 °C
• Clock Source Options
– Oscillator XOSC — Very low-power, 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 reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supports bus frequencies from 1 MHz to 10 MHz
• 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; selectable trip points
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash block protection
• Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting during in-circuit debugging
• Peripherals
– ADC — 8-channel, 12-bit resolution; 2.5 μs conversion time; automatic compare function; 1.7 mV/°C temperature sensor; internal bandgap reference channel; operation in stop3; fully functional from 3.6 V to 1.8 V.
– 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 tied internally to TPM input capture; operation in stop3
– TPM — One 1-channel timer/pulse-width modulator TPM module; selectable input capture, output compare, or buffered edge- or center-aligned PWM on each channel; ACMP output can be tied internally to input capture
– MTIM — 8-bit modulo timer module with optional prescaler
– RTC — Real-time counter 8-bit modulo 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 wakeup without external components; runs in all MCU modes
– SCI — Full duplex non-return to zero NRZ; LIN master extended break generation; LIN slave extended break detection; wakeup on active edge
– KBI — 8-pin keyboard interrupt with selectable edge
and level detection modes
• Input/Output
– 22 GPIOs and one input-only and one output-only pin.
– Hysteresis and configurable pullup device on all input pins; configurable slew rate and drive strength on all output pins except PTA5.
• Package Options
– 28-pin SOIC, 24-pin QFN, 16-pin TSSOP
