Product details
Overview
MC68336GCAB25 from NXP (formerly Motorola) is a 16-bit CISC microcontroller with integrated Time Processing Unit (TPU), 20.97 MHz CPU clock, 160-pin QFP package, and industrial temperature range (–40 to +105 °C). It serves as a real-time control engine in embedded motion systems requiring deterministic I/O timing.
For engineers reviewing the MC68336GCAB25 datasheet, MC68336GCAB25 pinout, MC68336GCAB25 application, or MC68336GCAB25 equivalent, key selection criteria include TPU-based PWM generation, 16-bit external bus interface with CS0–CS10 chip selects, analog input capability (AN0–AN59), and CAN-ready pin compatibility with MC68376.
Technical Context
The MC68336GCAB25 implements a 16-bit M68K core with on-chip TPU for autonomous time-critical I/O handling-enabling precise pulse-width modulation, quadrature decoding, and event capture without CPU intervention. Its memory controller supports 16-bit data/24-bit address bus, eight programmable chip selects, and dynamic bus sizing (SIZ0/SIZ1).
It integrates dual 16-bit parallel ports (PE and PF), 60-channel analog input multiplexer (AN0–AN59), and dedicated TPU clock inputs (CTM2C, CTD3–CTD10, CPWM5–CPWM8). The device lacks on-chip CAN transceiver but shares pin-compatible layout with MC68376 for upgrade path.

FAQ
What is the maximum operating frequency of the MC68336GCAB25?
The MC68336GCAB25 operates at a maximum CPU clock frequency of 20.97 MHz, derived from an external crystal (XTAL/EXTAL) and internal PLL. This frequency is fixed per the GCAB25 suffix and validated across the –40 °C to +105 °C temperature range. The MC68336GCAB25 does not support user-adjustable clock multipliers beyond its factory-configured PLL ratio.
Does the MC68336GCAB25 include an on-chip CAN controller?
No, the MC68336GCAB25 does not integrate a CAN controller. It shares pin compatibility with the MC68376-which does include CAN-but lacks the CANRX0/CANTX0 signals and associated register set. The MC68336GCAB25 can interface with external CAN transceivers via GPIO or serial ports, but protocol handling requires software implementation.
How many analog input channels does the MC68336GCAB25 support?
The MC68336GCAB25 supports 60 analog input channels (AN0 through AN59), routed to a single 10-bit successive-approximation ADC. These inputs are multiplexed through dedicated pins with separate high/low reference inputs (VRH/VRL) and analog power rails (VDDA/VSSA) to maintain accuracy across temperature and noise conditions.
What package type and dimensions does the MC68336GCAB25 use?
The MC68336GCAB25 uses a 160-pin plastic quad flat pack (QFP) per Case 864A-03 mechanical specification: 28.0 mm × 28.0 mm body size, 0.65 mm lead pitch, and 1.60 mm maximum height. Pins 1 and 160 are No Connect (NC) for revision D+ silicon to ensure pin alignment with MC68376.
Is the MC68336GCAB25 pin-compatible with the MC68376?
Yes, the MC68336GCAB25 is pin-compatible with the MC68376 for revision D and later silicon (F60K+ mask sets), where pins 1 and 160 are designated NC. However, functional compatibility is partial: the MC68336GCAB25 lacks CANRX0/CANTX0 and related registers present in MC68376, so hardware layout may be shared but firmware is not interchangeable.
