NXP Semiconductors MC9S08PA16VLCR

Overview

MC9S08PA16VLCR from NXP Semiconductors is an 8-bit S08 core 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 - deployed in automotive body control modules, industrial sensor nodes, and smart appliance motor controllers.

For engineers reviewing the MC9S08PA16VLCR datasheet, MC9S08PA16VLCR pinout, MC9S08PA16VLCR application, or MC9S08PA16VLCR equivalent, key selection criteria include its 32-pin LQFP package, 20 mA high-drive GPIO capability, stop3-mode current of 1.3 µA, on-chip ICE debug support, and VDD range of 2.7–5.5 V for robust operation in noisy embedded environments.

Technical Context

The MC9S08PA16VLCR implements an S08 CPU core with four-level nested interrupt handling and up to 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 1% internal reference accuracy over 0–70 °C.

System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access protection. Peripheral clock gating via the peripheral clock enable register allows selective module power-down in low-power modes including stop3.

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PA16VLCR?

The MC9S08PA16VLCR operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, fully specified over the industrial temperature range of –40 °C to 105 °C. Its internal clock source (ICS) with FLL achieves this performance using either internal trimming or external crystal reference, maintaining timing integrity under varying load and temperature conditions.

Does the MC9S08PA16VLCR support in-circuit debugging, and what interface does it use?

Yes, the MC9S08PA16VLCR includes an on-chip in-circuit emulator (ICE) debug module and supports single-wire background debug mode (BDM) via the BKGD pin. It provides three hardware breakpoints, two comparators, and nine trigger modes - enabling full visibility into program flow, register states, and memory contents during development without requiring dedicated debug headers.

How many GPIOs does the MC9S08PA16VLCR offer in its 32-pin LQFP package?

The MC9S08PA16VLCR in the 32-pin LQFP package provides 28 GPIOs, including eight keyboard interrupt inputs (KBI0P0–KBI0P7), two true open-drain outputs (PTA2, PTA3), and four ultra-high-current pins (PTB4, PTB5, PTD0, PTD1) capable of 20 mA sink/source - all configurable via standard port control registers.

What low-power modes are available on the MC9S08PA16VLCR, and what is the lowest current draw?

The MC9S08PA16VLCR supports multiple low-power modes including wait and stop3. In stop3 mode - where only the 1 kHz LPO clock remains active - typical supply current is 1.3 µA at 5 V. Optional peripherals like LVD or ADC add ≤128 µA or ≤40 µA respectively, making it suitable for multi-year battery operation in intermittent-sensing applications.

Is the MC9S08PA16VLCR pin-compatible with other members of the PA-series, such as the MC9S08PA8VLCR?

No, the MC9S08PA16VLCR is not pin-compatible with the MC9S08PA8VLCR despite sharing the same 32-pin LQFP package. While both use identical pinouts, the MC9S08PA8VLCR omits certain peripheral functions (e.g., reduced ADC channels, fewer FTM channels) and has different memory mapping - requiring firmware and peripheral initialization adjustments even if physically mounted.
