FAQ
What is the maximum bus frequency supported by the MC9S08DN16ACLC?
The MC9S08DN16ACLC supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a 2:1 divider. This frequency is achievable using the MCG's PLL or FLL modes with appropriate external crystal or internal reference configuration. The MC9S08DN16ACLC maintains full peripheral functionality-including ADC timing, SCI baud rate generation, and TPM PWM resolution-at this speed across its specified voltage and temperature range.
Does the MC9S08DN16ACLC include a temperature sensor?
Yes, the MC9S08DN16ACLC integrates a factory-calibrated on-die temperature sensor accessible through the 12-bit ADC module. It is mapped as a dedicated ADC channel and uses the internal bandgap reference for ratiometric accuracy. This sensor enables closed-loop thermal monitoring in applications such as motor control and battery management without requiring external components. The MC9S08DN16ACLC datasheet specifies typical accuracy of ±3°C over –40°C to +105°C.
Can the MC9S08DN16ACLC operate in low-power stop modes with RTC wake-up?
Yes, the MC9S08DN16ACLC supports Stop2 and Stop3 modes with RTC wake-up enabled by its built-in 1 kHz low-power oscillator. In Stop3 mode, current consumption drops below 1 µA while retaining RTC counting and wake-up capability. The MC9S08DN16ACLC allows programmable wake-up intervals from milliseconds to hours using the 8-bit modulus counter and prescaler, making it suitable for battery-powered sensor polling applications.
What debug interface does the MC9S08DN16ACLC provide?
The MC9S08DN16ACLC features a single-wire background debug (BDM) interface compliant with Freescale/NXP BDM protocol. It supports full in-circuit emulation, real-time bus capture, flash programming, and breakpoint debugging without halting system clocks. This interface uses the BKGD/MS pin and requires no additional debug headers or JTAG adapter-reducing development tool cost. The MC9S08DN16ACLC also includes on-chip ICE resources for trace and timing analysis during firmware validation.
Is the MC9S08DN16ACLC LIN 2.0 compliant?
Yes, the MC9S08DN16ACLC SCI1 module implements LIN 2.0 Protocol and SAE J2602 conformance, including master extended break generation, slave extended break detection, and wakeup-on-active-edge functionality. Its baud rate generator supports standard LIN frequencies (e.g., 19.2 kbps) with hardware synchronization. The MC9S08DN16ACLC meets physical layer timing requirements when paired with an external LIN transceiver, enabling direct integration into automotive body networks.
