Freescale Semiconductor, Inc.
• On-chip in-application programmable FLASH memory
• On-chip random-access memory (RAM)
• • 2-channel, 16-bit timer interface module (TIM)
• • 4-channel, 8-bit analog-to-digital converter (ADC) on
MC68HC908QY2, MC68HC908QY4, MC68HC908QT2, and
MC68HC908QT4
• 5 or 13 bidirectional input/output (I/O) lines, and one input only
• 6-bit keyboard interrupt with walk-up feature (KBI)
• Low-voltage inhibit (LVI) module
• System protection features
• External asynchronous interrupt pin with internal pull-up (IRQ)
shared with general-purpose input pin
• Master asynchronous reset pin (RST) shared with
general-purpose input/output (I/O) pin
• Power-on reset
• Power saving stop and wait modes
• MC68HC908QY4, MC68HC908QY2, and MC68HC908QY1 are
available in these packages:
– 16-pin plastic dual in-line package (PDIP)
– 16-pin small outline integrated circuit (SOIC) package
– 16-pin thin shrink small outline package (TSSOP)
• • MC68HC908QT4, MC68HC908QT2, and MC68HC908QT1 are
available in these packages:
– 8-pin PDIP
– 8-pin SOIC
– 8-pin dual flat no lead (DFN) package
The BLDC motor control application requires six PWM outputs, three
Hall position sensor inputs and an ADC channel for voltage
measurements as a minimum. Therefore 16-pin MC68HC908QY2 or
MC68HC908QY4, that accommodate ADC, are the right choice.
