Product details
Overview
MC9S08PL8CTG from NXP Semiconductors is an 8-bit S08 microcontroller designed for cost-sensitive industrial and automotive body electronics applications. It features 8 KB flash, 2 KB RAM, 256-byte EEPROM, 10-bit ADC with 12 channels, one analog comparator, two SCI (LIN-capable) interfaces, I²C, CRC module, and dual FlexTimer modules (6-channel + 2-channel). It operates at up to 20 MHz across –40 °C to +85 °C with supply voltage 2.7–5.5 V.
For engineers reviewing the MC9S08PL8CTG datasheet, MC9S08PL8CTG pinout, MC9S08PL8CTG application, or MC9S08PL8CTG equivalent, this page delivers verified specifications, package mapping to 16-pin TSSOP, validated peripheral capabilities including stop3-mode current (1.3 µA), real-time clock support, and confirmed alternative options for migration or second sourcing.
Technical Context
The MC9S08PL8CTG implements the HCS08 CPU core with four-level nested interrupt handling and supports multiple clock sources: external crystal/resonator (31.25 kHz–20 MHz) and internal ICS with FLL, delivering up to 20 MHz bus frequency with ±2% accuracy over –40 °C to +85 °C. Its memory protection unit enforces flash/RAM access control, while the background debug interface enables single-wire in-circuit debugging with three breakpoints.
Peripherals include a 12-channel 10-bit ADC with hardware trigger and stop-mode operation, two FlexTimer modules supporting input capture, output compare, and PWM, and dual SCI modules with LIN 2.1 extension support. System-level protection includes watchdog with independent LPO clock, configurable low-voltage detect/warning, and illegal opcode/address detection with reset.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08PL8CTG | Same silicon die and pinout; rebranded by NXP post-SFSG acquisition - identical electrical specs, memory map, and debug interface | No functional difference; used interchangeably in legacy designs and new BOMs where SFSG branding is preferred | Select S9S08PL8CTG when sourcing from distributors listing SFSG-part-numbered stock; full drop-in replacement with identical documentation |
| MC9S08PL8CLC | Same core and peripherals but in 32-pin LQFP package with 30 GPIOs (vs. 14 on MC9S08PL8CTG); higher thermal resistance (88 °C/W vs. 130 °C/W) | Better suited for designs requiring more I/O expansion or higher ambient operating margins; not pin-compatible due to different package and pin count | Choose MC9S08PL8CLC when board layout allows larger footprint and additional GPIOs are needed; requires PCB redesign |
Compared with S9S08PL8CTG, the MC9S08PL8CTG offers identical functionality with no trade-offs, while MC9S08PL8CLC provides expanded I/O at the cost of footprint size and thermal performance - making the CTG variant optimal for space-constrained, thermally managed applications like door modules and sensor nodes.

FAQ
What is the maximum operating frequency of the MC9S08PL8CTG?
The MC9S08PL8CTG supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7–5.5 V) and temperature range (–40 °C to +85 °C). This is achieved using either the internal ICS with FLL or external crystal/resonator sources, with frequency stability maintained via factory-trimmed internal reference and ±2% DCO deviation over temperature.
Does the MC9S08PL8CTG support LIN communication?
Yes, the MC9S08PL8CTG supports LIN 2.1 communication through its two SCI modules, both featuring optional 13-bit break detection, NRZ framing, and automatic wakeup capability. These modules operate independently and can serve as LIN master or slave nodes without external transceivers when paired with appropriate level-shifting circuitry.
What is the stop-mode current consumption of the MC9S08PL8CTG?
The MC9S08PL8CTG achieves 1.3 µA typical supply current in Stop3 mode at 5 V and –40 °C to +85 °C, with only the 1 kHz LPO clock active. This ultra-low quiescent current enables battery-backed real-time clock operation and wake-on-IRQ functionality in energy-sensitive applications such as wireless sensor nodes and automotive standby systems.
How many ADC channels does the MC9S08PL8CTG have, and what is their resolution?
The MC9S08PL8CTG integrates a 12-channel, 10-bit successive-approximation ADC with 2.5 µs conversion time, internal bandgap reference, data buffers with watermark flag, and automatic compare function. All 12 channels are accessible on the 16-pin TSSOP package via dedicated pins or multiplexed GPIOs, and the ADC remains operational in stop mode when configured appropriately.
Is the MC9S08PL8CTG pin-compatible with other members of the S08PL family?
The MC9S08PL8CTG is pin-compatible with other 16-pin TSSOP variants in the S08PL family, including MC9S08PL8CTJ (20-TSSOP) and MC9S08PL16CTG (same package but 16 KB flash). However, it is not pin-compatible with 32-pin LQFP or 44-pin LQFP variants due to differing pin counts and signal mappings - always verify pin assignment tables before substitution.
