Product details
Overview
S9S08RN16W2MTG from NXP Semiconductors (formerly Freescale) is an 8-bit S08 microcontroller with 16 KB flash, 256-byte EEPROM with ECC, and 2 KB RAM, operating at up to 20 MHz bus frequency across –40 °C to +125 °C. It integrates ADC (10-bit, 8-channel), two SCI/UARTs, I²C, SPI, FTM timers, TSI touch sensing, and low-power stop3 mode consuming only 4.6 µA - deployed in automotive body control modules, industrial sensor nodes, and HVAC actuator interfaces.
For engineers reviewing the S9S08RN16W2MTG datasheet, S9S08RN16W2MTG pinout, S9S08RN16W2MTG application, or S9S08RN16W2MTG equivalent, this page delivers verified technical context, package-specific pin assignments, real-world use-value per application, and two validated alternative parts - all grounded in the official S9S08RN16DS Rev 1 (02/2014) specification.
Technical Context
The S9S08RN16W2MTG implements an enhanced S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a Pierce oscillator (XOSC) for crystal/resonator operation and an internal clock source (ICS) with FLL, delivering ±2% DCO frequency deviation over –40 °C to 125 °C.
System protection includes independent watchdog timer, configurable low-voltage detect (LVD) with four warning thresholds per range, illegal opcode/address detection, and flash/RAM access protection. Debug is enabled via single-wire BDM interface with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08RN8W2MTG | 8 KB flash, 128-byte EEPROM, same 16-pin TSSOP package and peripheral set | Lower memory capacity limits firmware complexity; suitable for cost-sensitive, function-limited designs | Select when application firmware fits within 8 KB and no future memory expansion is anticipated |
| S9S08RN16W2MLF | Same 16 KB flash and peripherals, but in 48-pin LQFP package with 35 GPIOs and full 12-channel ADC | Enables larger I/O count and higher-resolution analog acquisition; requires PCB redesign | Choose when design needs >16 pins or 12-bit ADC channels; not drop-in compatible with TG package |
Compared with MC9S08RN8W2MTG, the S9S08RN16W2MTG doubles flash and EEPROM while retaining identical package and low-power behavior; versus S9S08RN16W2MLF, it trades I/O count and ADC channel count for compact 16-pin footprint - making it optimal for space-constrained, memory-moderate embedded control.

FAQ
What is the maximum bus frequency supported by the S9S08RN16W2MTG?
The S9S08RN16W2MTG 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 +125 °C). This is achieved using the internal clock source (ICS) with FLL or external crystal oscillator (XOSC), and is confirmed in Table 5 of the S9S08RN16DS Rev 1 datasheet under "Bus frequency".
Does the S9S08RN16W2MTG support in-circuit debugging, and what interface is used?
Yes, the S9S08RN16W2MTG supports in-circuit debugging via a single-wire background debug mode (BDM) interface. It includes breakpoint capability for up to three breakpoints and an on-chip in-circuit emulator (ICE) module with two comparators and nine trigger modes - all documented in Section 1.3 ("Development support") of the S9S08RN16DS Rev 1 datasheet.
What are the low-power consumption characteristics of the S9S08RN16W2MTG in Stop3 mode?
In Stop3 mode, the S9S08RN16W2MTG draws 4.6 µA at 5 V (–40 °C to +125 °C). Adding active peripherals increases current: +40 µA for ADC, +121 µA for TSI, and +128 µA for LVD - all specified in Table 4 of the S9S08RN16DS Rev 1 datasheet. The 1 kHz LPO clock remains active to support wake events.
Which package type does the S9S08RN16W2MTG use, and what are its thermal characteristics?
The S9S08RN16W2MTG uses a 16-pin TSSOP package (designator "TG"). Its thermal resistance is θJA = 130 °C/W on a single-layer board and 87 °C/W on a four-layer board, as listed in Table 8 of the S9S08RN16DS Rev 1 datasheet. The device is rated for junction temperatures up to +135 °C.
Can the S9S08RN16W2MTG perform analog-to-digital conversion while in low-power mode?
Yes, the S9S08RN16W2MTG supports ADC operation in Stop3 mode. Its 8-channel, 10-bit ADC can be triggered and acquire data while the CPU and most peripherals are halted - enabling precise sensor sampling with minimal power overhead. This capability is explicitly stated in the "Peripherals" section of the S9S08RN16DS Rev 1 datasheet.
