FAQ

What is the maximum operating frequency of the MC9S08JM60CLH CPU core?

The MC9S08JM60CLH CPU core operates at up to 48 MHz, with a corresponding 24 MHz internal bus frequency. This timing enables deterministic execution of real-time control tasks while maintaining compatibility with USB full-speed timing requirements through the MCG clock generator's PLL mode. The MC9S08JM60CLH achieves this performance within its specified voltage and temperature range without requiring external frequency multipliers.

Does the MC9S08JM60CLH include an integrated USB physical layer?

Yes, the MC9S08JM60CLH integrates a full-speed USB 2.0 transceiver, including differential drivers/receivers, on-chip 3.3-V regulator (VUSB33), and USBDP pull-up resistor. This eliminates the need for an external USB PHY chip, reducing system cost and PCB area. The MC9S08JM60CLH supports control, interrupt, isochronous, and bulk transfers across seven endpoints, with endpoint 0 and six additional configurable endpoints.

What power-saving modes does the MC9S08JM60CLH support, and which peripherals remain active in Stop3 mode?

The MC9S08JM60CLH supports Wait, Stop2, and Stop3 modes. In Stop3 mode, the real-time counter (RTC), analog comparator (ACMP), and internal low-frequency oscillator remain operational while CPU and most peripherals halt. This enables wake-on-compare events or periodic RTC interrupts with typical current draw below 1 µA. The MC9S08JM60CLH maintains RAM retention and register state across all stop modes.

How many general-purpose I/O pins does the MC9S08JM60CLH provide, and what configuration options are available?

The MC9S08JM60CLH provides up to 51 general-purpose I/O pins across Ports A–G. Each pin supports software-selectable internal pullups, slew rate control, and drive strength settings. Input/output direction is configurable per pin, and port pins retain their state during low-power modes unless explicitly disabled. The MC9S08JM60CLH also includes dedicated reset, IRQ, and BKGD/MS pins with internal pullups to minimize external component count.

Is the MC9S08JM60CLH pin-compatible with other members of the JM-series, such as the MC9S08JM32CLH?

Yes, the MC9S08JM60CLH and MC9S08JM32CLH share identical 64-pin LQFP packaging, pin assignments, peripheral mapping, and electrical characteristics. They differ only in flash size (60 KB vs. 32 KB) and part number marking. Firmware compiled for MC9S08JM60CLH will run on MC9S08JM32CLH if code size fits, making the MC9S08JM60CLH a direct upgrade path without PCB redesign.
