Description
The MC9S08PA4AVTG is an 8-bit microcontroller that runs at a maximum frequency of 20MHz and is based on an improved S08 CPU (20MHz bus). The chip has 14 general-purpose I/O pins, an 8-channel 12-bit A/D converter, 4kB internal flash, and 512kB internal RAM. Additionally, this device includes add-ons like a 16-bit real time clock and a serial communication interface (SCI/UART) module (RTC). The device can function between 2.7 and 5.5V.
Features
– Oscillator (XOSC) - loop-controlled Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 39.0625 kHz or 4 MHz to 20 MHz
– Internal clock source (ICS) - containing a frequency locked-loop (FLL) controlled by internal or external reference; precision trimming of internal reference allowing 1% deviation across a temperature range of 0°C to 70°C and 2% deviation across whole operating temperature range; up to 20 MHz
– Watchdog with independent clock source
– Low-voltage detection with reset or interrupt; selectable trip points
– Illegal opcode detection with reset
– Illegal address detection with reset
– Up to 20 MHz bus at 2.7 V to 5.5 V across operating temperature range
– Supporting up to 40 interrupt/reset sources
– Supporting up to four-level nested interrupt
– On-chip memory
– Up to 4 KB flash read/program/erase over full operating voltage and temperature
– Up to 128 byte EEPROM; 2-byte erase sector; program and erase while executing flash
– Up to 512 byte random-access memory (RAM)
– Flash and RAM access protection
– One low-power stop mode; reduced power wait mode
– Peripheral clock enable register can disable clocks to unused modules, reducing currents; allows clocks to remain enabled to specific peripherals in stop3 mode
