Pin Functions
PIN NAME | PIN DESCRIPTION |
VDD | Power supply input to the MCU. |
VSS | Power supply ground. |
VDD3 | 3.3V regulated output from the MCU. |
VSS1 | Power supply ground. |
OSC1 OSC2 | Connections to the on-chip oscillator. An external clock can be connected directly to OSC1; with OSC2 floating. These are 3.3V pins. |
RST | A logic 0 on the RST pin forces the MCU to a known startup state. RST is bidirectional, allowing a reset of the entire system. It is driven low when any internal reset source is asserted. This pin contains an internal pullup resistor. |
IRQ | External IRQ pin; with software programmable internal pull-up and schmitt trigger input. This pin is also used for mode entry selection. |
VSYNC | Vsync input to the sync processor. |
HSYNC | Hsync input to the sync processor. |
PTA7/PWM15–PTA0/PWM8 | These are shared-function pins. Each pin can be configured as a standard I/O pin or a PWM output channel. |
PTB7/PWM7–PTB0/PWM0 | These are shared-function pins. Each pin can be configured as a standard I/O pin or a PWM output channel. |
PTC5/ADC5–PTC0/ADC0 | These are shared-function pins. Each pin can be configured as a standard I/O pin or an ADC input channel. |
PTD6/IICSDA | This is a shared function pin. It can be configured as a standard I/O pin or the data line of the multimaster IIC module. This pin is open-drain when configured as output. |
PTD5/IICSCL | This is a shared function pin. It can be configured as a standard I/O pin or the clock line of the multimaster IIC module. This pin is open-drain when configured as output. |
PTD4/CLAMP | This is a shared function pin. It can be configured as a standard I/O pin or the clamp output from the sync processor. |
PTD3/DDCSCL | This is a shared function pin. It can be configured as a standard I/O pin or as the clock line of the DDC12AB module. This pin is open-drain when configured as output. |
PTD2/DDCSDA | This is a shared function pin. It can be configured as a standard I/O pin or the data line of the DDC12AB module. This pin is open-drain when configured as output. |
PTD1/D– PTD0/D+ | These are 3.3V, shared function pins. The pins can be configured as standard I/O pins or USB interface differential data lines. |
Description
The MC68HC908BD48 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
With special modules such as the sync processor, analog-to-digital converter, pulse modulator module, DDC12AB interface, multi-master IIC interface, and universal serial bus interface, the MC68HC908BD48 is designed specifically for use in digital monitor systems.
