MC9S08LC60 Features

8-Bit HCS08 Central Processor Unit (CPU)

• 40-MHz HCS08 CPU
• HC08 instruction set with added BGND instruction
• Background debugging system
• Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
• In-Circuit Emulator (ICE) debug module containing two comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data. ICE debug module supports both tag and force breakpoints.
• Support for up to 32 interrupt/reset sources

Memory Options

• Dual on-chip in-circuit programmable FLASH memories with block protection and security options; 60K and 36K options available
• Program/erase of one FLASH array while executing from another
• On-chip random-access memory (RAM); 4K and 2.5K options available

Power-Saving Features

• Wait plus three stops
• Software disable of clock monitor and low-voltage interrupt (LVI) for lowest stop current
• Software-generated real-time clock (RTC) functions using real-time interrupt (RTI)

Configurable Clock Source

• Clock source options include crystal, resonator, external clock, or internally generated clock with precision nonvolatile memory (NVM) trimming
• Automatic clock monitor function

System Protection

• Optional computer operating properly (COP) reset
• Low-voltage detection with reset or interrupt
• Illegal opcode detection with reset

Package Options

• 64-pin low-profile quad flat package (LQFP)
• 80-pin LQFP

Peripherals

• LCD (liquid crystal display driver) — Compatible with 5-V or 3-V LCD glass displays; functional in wait and stop3 low-power modes; selectable frontplane and backplane configurations:
  • – 4 x 40 or 3 x 41 (80-pin package)
  • – 4 x 32 or 3 x 33 (64-pin package)
• ACMP (analog comparator) — option to compare to internal reference voltage; output is software selectable to be driven to the input capture of TPM1 channel 0.
• ADC (analog-to-digital converter) — 8-channel, 12- bit with automatic compare function, asynchronous clock source, temperature sensor and internal bandgap reference channel. ADC is hardware triggerable using the RTI counter.
• SCI (serial communications interface) — available single-wire mode
• SPI1 and SPI2 — Two serial peripheral interface modules
• KBI — Two 8-pin keyboard interrupt modules with software selectable rising or falling edge detect
• IIC — Inter-integrated circuit bus module capable of operation up to 100 kbps with maximum bus loading; capable of higher baudrates with reduced loading
• TPM1 and TPM2 — Two timer/pulse-width modulators with selectable input capture, output compare, and edge-aligned PWM capability on each channel. Each timer module may be configured for buffered, centered PWM (CPWM) on all channels.

Input/Output

• Up to 24 general-purpose input/output (I/O) pins; includes two output-only pins and one input-only pin
• Software selectable pullups on ports when used as input. Selection is on an individual port bit basis.
• Software selectable slew rate control on ports when used as outputs (selection is on an individual port bit basis)
• Software selectable drive strength control on ports when used as outputs (selection is on an individual port bit basis)
• Internal pullup on RESET and IRQ pin to reduce customer system cost

Absolute Maximum Ratings

1. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive (VDD) and negative (VSS) clamp voltages, then use the larger of the two resistance values.
2. All functional non-supply pins are internally clamped to VSS and VDD.
3. Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result in external power supply going out of regulation. Ensure external VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is present, or if the clock rate is very low which would reduce overall power consumption.
