Product details
Overview
MC9S08PL16CTJ 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 +85 °C. It integrates dual FlexTimer modules (6-channel + 2-channel), two SCI/LIN UARTs, I²C, 12-channel 10-bit ADC, analog comparator, RTC, and CRC engine - designed for cost-sensitive industrial control and automotive body electronics.
For engineers reviewing the MC9S08PL16CTJ datasheet, MC9S08PL16CTJ pinout, MC9S08PL16CTJ application, or MC9S08PL16CTJ equivalent, this page delivers verified electrical specs, package mapping to 20-pin TSSOP, validated peripheral timing, low-power stop3 mode current (1.3 µA), and real-world use cases in motor control, sensor interface, and LIN bus node design.
Technical Context
The MC9S08PL16CTJ implements an enhanced HCS08 core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a 31.25 kHz–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) featuring a frequency-locked loop (FLL) with factory-trimmed internal reference (±2% deviation over –40 °C to +85 °C).
System protection includes independent watchdog timer, 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 retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08PL16CLC | 32-pin LQFP package; higher thermal performance (RθJA = 88 °C/W single-layer); 30 GPIO vs. 14 on CTJ | Suitable for designs requiring more I/O or better heat dissipation in industrial enclosures | Select CLC when board layout allows larger footprint and additional GPIOs are needed for expansion. |
| S9KEAZ128AMLH | ARM Cortex-M0+ core; 128 KB flash; 16 KB RAM; higher performance but no native LIN support | Targets next-generation designs needing upgrade path beyond 8-bit, with USB or CAN requirements | Choose S9KEAZ128AMLH only if migrating to 32-bit architecture and accepting software rework; not drop-in compatible. |
Compared with MC9S08PL16CTJ, the CLC variant offers greater I/O count and thermal margin in LQFP, while the S9KEAZ128AMLH represents a platform shift to ARM with expanded memory but loss of LIN-native UART and increased BOM cost.

FAQ
What is the maximum bus frequency supported by the MC9S08PL16CTJ?
The MC9S08PL16CTJ 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 +85 °C). This frequency is achievable using either the internal clock source (ICS) with FLL or an external crystal/resonator connected to the XOSC circuit. The device maintains timing compliance under all specified conditions without derating.
Does the MC9S08PL16CTJ support LIN bus communication?
Yes, the MC9S08PL16CTJ supports LIN bus communication through its two Serial Communication Interface (SCI) modules, both explicitly documented as LIN-capable in the datasheet. Each SCI includes optional 13-bit break detection and NRZ framing required for LIN 2.x compliance, enabling use as a LIN slave node in automotive body electronics without external transceivers.
What low-power modes are available on the MC9S08PL16CTJ, and what is the lowest current draw?
The MC9S08PL16CTJ offers multiple low-power modes including Wait and Stop3. In Stop3 mode - where only the 1 kHz LPO clock remains active - the device draws just 1.35 µA at 5 V and –40 °C to +85 °C. This mode retains RAM contents, RTC operation, and wake-up capability via IRQ, KBI, or ACMP, making it ideal for battery-powered sensor nodes.
Can the MC9S08PL16CTJ execute code while erasing or programming flash memory?
Yes, the MC9S08PL16CTJ supports read-while-write (RWW) functionality: it can execute code from flash while simultaneously programming or erasing other flash sectors. This capability enables safe in-field firmware updates and data logging without halting real-time control tasks - a critical feature for automotive and industrial applications requiring continuous operation.
What is the package type and pin count of the MC9S08PL16CTJ?
The MC9S08PL16CTJ uses a 20-pin Thin Shrink Small Outline Package (TSSOP) with 0.65 mm lead pitch. This package is confirmed in the official NXP datasheet (Rev. 5, June 2020), Table 1 "Ordering Information", and corresponds to the "TJ" suffix in the part number format. It provides 14 GPIOs plus dedicated analog, timer, and communication pins in a compact footprint.
