NXP Semiconductors MC9S08PA16AVLC

Overview

MC9S08PA16AVLC 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 FlexTimer modules (6-channel + 2-channel), 12-bit 12-channel ADC, I²C, two SCI/LIN UARTs, SPI, RTC, and analog comparator - deployed in automotive body control modules requiring robust low-power operation and mixed-signal integration.

For engineers reviewing the MC9S08PA16AVLC datasheet, MC9S08PA16AVLC pinout, MC9S08PA16AVLC application, or MC9S08PA16AVLC equivalent, this page delivers verified electrical specs, validated package mapping (32-pin LQFP), confirmed peripheral timing behavior, and real-world use context for industrial and automotive embedded design.

Technical Context

The MC9S08PA16AVLC implements an S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a Pierce oscillator (XOSC) for 4–20 MHz crystals 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 protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access protection. Power management supports Stop3 mode with <1.35 µA supply current and peripheral clock gating via the peripheral clock enable register.

FAQ

What is the maximum bus frequency supported by the MC9S08PA16AVLC?

The MC9S08PA16AVLC supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7 V to 5.5 V) and temperature range (–40 °C to +105 °C). This is achieved using either the internal clock source (ICS) with FLL or an external crystal oscillator (XOSC) in the 4–20 MHz range, as specified in Section 7.1 of the Rev. 4 datasheet.

Does the MC9S08PA16AVLC support LIN communication?

Yes, the MC9S08PA16AVLC supports LIN communication through both SCI0 and SCI1 modules, which include optional 13-bit break detection and NRZ encoding required for LIN 2.x compliance. The datasheet explicitly lists "SCI (LIN Capable)" in Table 1 and confirms LIN extension support in the SCI peripheral description.

What package type is used for the MC9S08PA16AVLC?

The MC9S08PA16AVLC uses a 32-pin LQFP package (designator "LC" per part number format), with 0.8 mm lead pitch and 7 mm × 7 mm body size. This is confirmed in Table 1 (Ordering Information) and Section 8 (Dimensions) of the MC9S08PA16 Series Data Sheet Rev. 4.

How much EEPROM memory does the MC9S08PA16AVLC include?

The MC9S08PA16AVLC includes 256 bytes of on-chip EEPROM organized in 2-byte erase sectors. It supports program and erase operations while executing code from flash memory, as documented in the Key Features section and Table 1 of the datasheet.

Can the MC9S08PA16AVLC operate in low-power Stop3 mode with ADC enabled?

Yes, the MC9S08PA16AVLC supports ADC operation in Stop3 mode when configured with ADLPC = 1, ADLSMP = 1, ADCO = 1, MODE = 10B, and ADICLK = 11B. In this configuration, the ADC adds only 40 µA to the base Stop3 current of 1.35 µA (at 5 V), as specified in Table 5, item #7 of the datasheet.
