Product details
Overview
MC9S08PT8VLD from NXP Semiconductors is an 8-bit S08 microcontroller with 8 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates ADC (12-channel, 12-bit), dual FTM modules, SCI/I²C/SPI interfaces, TSI for touch sensing, and low-power stop3 mode. Used in industrial control panels requiring robust timing, analog monitoring, and capacitive user interface.
For engineers reviewing the MC9S08PT8VLD datasheet, MC9S08PT8VLD pinout, MC9S08PT8VLD application, or MC9S08PT8VLD equivalent, this page delivers verified specifications, validated package mapping (44-pin LQFP), confirmed peripheral configuration, and two rigorously cross-checked alternative parts for functional substitution in embedded control designs.
Technical Context
The MC9S08PT8VLD implements an S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (4–20 MHz) and an internal ICS with FLL, enabling precise bus frequencies up to 20 MHz with ≤2% deviation over full temperature range.
System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access protection. Debug is supported via single-wire background debug interface with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

FAQ
What is the maximum operating frequency and voltage range for MC9S08PT8VLD?
The MC9S08PT8VLD operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with full specification compliance over the industrial temperature range of –40 °C to 105 °C. Its internal ICS with FLL maintains frequency stability within ±2% deviation across this entire range, and the external crystal oscillator supports 4–20 MHz crystals for precise timing-critical applications.
Does MC9S08PT8VLD support capacitive touch sensing, and how many electrodes can it handle?
Yes, MC9S08PT8VLD includes a dedicated Touch Sense Interface (TSI) module capable of supporting up to 16 external electrodes. It features configurable software or hardware scan triggers, full compatibility with NXP's touch sensing software library, and the ability to wake the MCU from stop3 mode upon electrode activity-enabling ultra-low-power human-machine interface implementations.
What are the low-power modes available on MC9S08PT8VLD, and what is the typical current draw in stop3 mode?
MC9S08PT8VLD offers multiple low-power states including reduced-power wait mode and stop3 mode. In stop3 mode-with only the 1 kHz LPO clock active-the typical supply current is 1.35 µA at 5 V and 1.3 µA at 3 V over –40 °C to 105 °C. Additional peripherals like ADC, TSI, and LVD can be selectively enabled with documented current adders (e.g., +40 µA for ADC, +121 µA for TSI).
Is MC9S08PT8VLD pin-compatible with MC9S08PT16VLD, and what are the implications for PCB design?
Yes, MC9S08PT8VLD and MC9S08PT16VLD share identical 44-pin LQFP package dimensions, pinout, and electrical characteristics. This allows direct PCB footprint reuse-designers can prototype with MC9S08PT8VLD and scale to MC9S08PT16VLD for larger firmware without layout changes, simplifying BOM management and reducing qualification effort across product variants.
What debug interface does MC9S08PT8VLD use, and what capabilities does it provide?
MC9S08PT8VLD uses a single-wire background debug (BDM) interface compliant with NXP's standard protocol. It supports in-circuit debugging with three hardware breakpoints, on-chip in-circuit emulator (ICE) functionality-including two comparators and nine trigger modes-and full flash programming/erasure. The BKGD/MS pin serves as the sole debug communication channel, minimizing PCB routing complexity.
