NXP Semiconductors MC9S08PT16AVLC

Overview

MC9S08PT16AVLC from NXP Semiconductors is an 8-bit S08 core microcontroller designed for cost-sensitive industrial and automotive control applications. It delivers 20 MHz bus operation across –40 °C to 105 °C, integrates 16 KB flash, 2 KB RAM, and 256 B EEPROM, and supports dual SCI (LIN-capable), I²C, SPI, two FTM modules, 12-channel 12-bit ADC, and touch-sensing interface (TSI) - enabling compact motor control and sensor node designs.

For engineers reviewing the MC9S08PT16AVLC datasheet, MC9S08PT16AVLC pinout, MC9S08PT16AVLC application, or MC9S08PT16AVLC equivalent, key selection considerations include its 32-pin LQFP package, ultra-high-current GPIO (20 mA sink/source), stop3 mode current of 1.3 µA, on-chip ICE debug support, and compatibility with NXP's touch sensing software library.

Technical Context

The MC9S08PT16AVLC implements an enhanced HCS08 CPU core with four-level nested interrupt handling and up to 40 interrupt/reset sources. Its clock system combines a precision internal clock source (ICS) with FLL and factory-trimmed reference (±1% over 0–70 °C), plus an external crystal oscillator supporting 4–20 MHz or 31.25–39.0625 kHz ranges.

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 integration features dual SCI with LIN extension, I²C at 400 kbps, CRC module, RTC, and TSI supporting up to 16 electrodes with wake-from-stop3 capability.

FAQ

What is the operating temperature range of the MC9S08PT16AVLC?

The MC9S08PT16AVLC is rated for continuous operation from –40 °C to +105 °C, validated across its full voltage range (2.7 V to 5.5 V). This extended temperature capability makes it suitable for under-hood automotive modules and industrial equipment exposed to thermal stress. All key parameters-including flash endurance, ADC accuracy, and stop3 mode current-are specified across this range per NXP MC9S08PT16 Rev. 4 datasheet.

Does the MC9S08PT16AVLC support in-circuit debugging?

Yes, the MC9S08PT16AVLC includes a single-wire background debug interface (BDM) with full on-chip in-circuit emulator (ICE) support. It provides three hardware breakpoints, two comparators, and nine trigger modes-enabling real-time code inspection, register monitoring, and non-intrusive execution control. Debugging requires no dedicated debug pins beyond BKGD/MS (PTA4), preserving all GPIO for application use.

How many touch-sensing electrodes does the MC9S08PT16AVLC support?

The MC9S08PT16AVLC supports up to 16 external touch-sensing electrodes via its integrated Touch Sense Interface (TSI) module. Electrodes are assigned to PTA6, PTA7, PTB0–PTB3, PTC0–PTC7, PTD2, PTD3, and PTE0–PTE3. The TSI can wake the MCU from stop3 mode, and its configuration is fully compatible with NXP's official touch sensing software library for rapid UI development.

What is the minimum supply current in stop3 mode for the MC9S08PT16AVLC?

The MC9S08PT16AVLC draws just 1.3 µA typical (5 V) in stop3 mode with only the 1 kHz LPO clock active. When adding TSI, ADC, or LVD functionality, incremental currents apply: +121 µA for TSI scan, +40 µA for ADC operation, and +128 µA for periodic LVD sampling. These values are measured across –40 °C to +105 °C and documented in Table 5 of the MC9S08PT16 Rev. 4 datasheet.

Which packages are available for the MC9S08PT16AVLC?

The MC9S08PT16AVLC is specifically offered in the 32-pin LQFP package (designator "LC"), measuring 7 mm × 7 mm with 0.8 mm pitch. While the broader MC9S08PT16 family includes 44-LQFP, 20-SOIC, 20-TSSOP, and 16-TSSOP variants, the "VLC" suffix unambiguously identifies the 32-pin LQFP version - confirmed in NXP's ordering information table (Table 1, Rev. 4).
