Product details
Overview
MC9S08PL16CTG from NXP Semiconductors is an 8-bit S08 core microcontroller with 16 KB flash, 256 B EEPROM, and 2 KB RAM, operating at up to 20 MHz across –40 °C to +85 °C. It integrates dual FlexTimer modules (6-channel + 2-channel), 12-channel 10-bit ADC, two SCI/UART interfaces with LIN support, I²C, RTC, and analog comparator - deployed in automotive body control modules and industrial sensor nodes.
For engineers reviewing the MC9S08PL16CTG datasheet, MC9S08PL16CTG pinout, MC9S08PL16CTG application, or MC9S08PL16CTG equivalent, key selection considerations include its 16-pin TSSOP package, single-wire background debug interface, stop3 mode current of 1.3 µA at 3 V, 10-bit ADC conversion time of 2.5 µs, and I²C operation up to 400 kbps.
Technical Context
The MC9S08PL16CTG implements an enhanced HCS08 CPU core with four-level nested interrupt handling and up to 40 interrupt/reset sources. Its clock system combines a Pierce oscillator (XOSC) supporting 31.25 kHz–20 MHz crystals/resonators and an internal clock source (ICS) with frequency-locked-loop (FLL), trimmed for ±1% accuracy from 0 °C to 70 °C and ±2% across –40 °C to 85 °C.
System protection includes independent watchdog clock, programmable low-voltage detect (LVD) with four warning thresholds per range, illegal opcode/address detection, and flash/RAM access protection. Peripheral clock gating via PMC enables selective module power-down in low-power modes including stop3 with 1 kHz LPO active.

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PL16CTG?
The MC9S08PL16CTG 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 +85 °C. Its internal clock source (ICS) with FLL achieves this frequency using either external crystal/resonator or internal reference, with ±2% accuracy across the full temperature range.
Does the MC9S08PL16CTG support in-circuit debugging, and what interface is used?
Yes, the MC9S08PL16CTG supports in-circuit debugging via a single-wire background debug interface (BKGD) on PTA4. It provides three hardware breakpoints and integrates an on-chip in-circuit emulator (ICE) with two comparators and nine trigger modes, enabling full visibility into program flow and register state without requiring dedicated JTAG pins.
What low-power modes does the MC9S08PL16CTG offer, and what is the lowest current consumption?
The MC9S08PL16CTG offers multiple low-power modes including reduced-power wait and stop3. In stop3 mode with only the 1 kHz LPO clock active, it draws just 1.3 µA at 3 V and –40 °C to +85 °C. Additional current adders apply for active peripherals like ADC (+40 µA) or LVD (+128 µA), all documented in the datasheet's supply current tables.
Can the MC9S08PL16CTG operate I²C peripherals directly, and what are the pin requirements?
Yes, the MC9S08PL16CTG includes a full-featured I²C module supporting up to 400 kbps, multi-master operation, and SMBus/PMBus protocols. Pins PTA2 (SDA1) and PTA3 (SCL1) are true open-drain outputs with internal weak pull-ups, eliminating need for external pull-up resistors in standard 3.3 V or 5 V bus configurations.
How is flash and EEPROM protected against accidental overwrite or corruption on the MC9S08PL16CTG?
The MC9S08PL16CTG implements flash and RAM access protection via the Flash Protection Register (FPROT) and Memory Protection Control Register (MPC). These registers allow selective locking of memory blocks, preventing unintended program/erase operations. EEPROM is further safeguarded by requiring specific command sequences and key values before write/erase execution.
