Technical Context

The S9S08SG16E1VTJ implements the HCS08 CPU core with BGND instruction support, 36 interrupt/reset sources, and a flexible internal clock source (ICS) featuring FLL-based frequency synthesis with ±1.5% deviation over –40°C to +125°C. Its memory map allocates 16,384 bytes of Flash (0x1860–0x7FFF), 1,024 bytes of RAM (0x0080–0x047F), and 26,528 unimplemented bytes.

Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and internal temperature sensor, two 2-channel TPM modules supporting edge- or center-aligned PWM, and a real-time counter (RTC) with free-running 1 kHz low-power oscillator usable in all MCU modes including Stop3.

FAQ

What is the maximum operating frequency of the S9S08SG16E1VTJ?

The S9S08SG16E1VTJ supports a maximum bus frequency of 40 MHz, achieved via its internal clock source (ICS) module with frequency-locked loop (FLL). This frequency is valid across the full operating temperature range of –40°C to +105°C, enabling deterministic real-time response in time-critical control loops without external clock components.

Does the S9S08SG16E1VTJ support in-circuit debugging?

Yes, the S9S08SG16E1VTJ features a single-wire background debug (BDM) interface on the BKGD/MS pin, enabling full in-circuit debugging, flash programming, and breakpoint execution. The on-chip debug module includes two comparators, nine trigger modes, and an eight-deep FIFO for flow tracing - all without requiring external JTAG hardware.

What are the Flash memory endurance and data retention specifications for the S9S08SG16E1VTJ?

The S9S08SG16E1VTJ Flash memory is rated for 100,000 program/erase cycles and guarantees 10 years of data retention at +85°C. These specifications apply across the full operating voltage (2.7–5.5 V) and temperature (–40°C to +105°C) ranges, and are validated per Freescale's Rev. 8/Rev. 9 MC9S08SG32 data sheet, Appendix A-16.

Can the S9S08SG16E1VTJ operate in low-power Stop modes while maintaining RTC functionality?

Yes, the S9S08SG16E1VTJ supports Stop3 mode, where the RTC continues running using its internal 1 kHz low-power oscillator. This enables time-of-day tracking, cyclic wake-up events, and calendar functions without external components or battery backup - critical for energy-efficient sensor nodes and alarm systems.

Is the S9S08SG16E1VTJ pin-compatible with other members of the MC9S08SGxx family?

Yes, the S9S08SG16E1VTJ is pin-compatible with MC9S08SG32E1VTJ and S9S08SG8E1VTJ in the 28-pin TSSOP package. All share identical pin assignments, electrical characteristics, and peripheral register maps - allowing drop-in replacement based solely on Flash size requirements without PCB redesign.
