Product details
Overview
MC9S08PA16AVTJR from NXP Semiconductors is an 8-bit S08 microcontroller with 16 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates dual FTM modules (6-channel + 2-channel), 12-bit 12-channel ADC, I²C, two SCI/LIN interfaces, SPI, RTC, and analog comparator - designed for automotive body control, industrial sensor nodes, and smart appliance motor management.
For engineers reviewing the MC9S08PA16AVTJR datasheet, MC9S08PA16AVTJR pinout, MC9S08PA16AVTJR application, or MC9S08PA16AVTJR equivalent, this page delivers verified electrical specs, package mapping to 20-pin TSSOP, validated peripheral timing, real-world use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MC9S08PA16AVTJR implements an S08 CPU core with nested interrupt support (up to four levels) and 40 interrupt/reset sources. Its clock system combines a 4–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) with FLL-based frequency multiplication, enabling precise 20 MHz bus operation with ±1% accuracy (0–70 °C) and ±2% (–40–105 °C).
System-level protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access control. Debug is enabled via single-wire background debug interface (BKGD) with three breakpoints and on-chip ICE module supporting nine trigger modes.
