NXP Semiconductors MC908GP16CBE

Overview

MC908GP16CBE from Freescale Semiconductor is an 8-bit HCS08-core microcontroller with 16 KB on-chip FLASH, 512 B RAM, and integrated peripherals including ADC (8-channel, 10-bit), SCI, SPI, and TIM modules. It operates at up to 8 MHz bus frequency, supports single-supply operation (2.7–5.5 V), and targets embedded control in industrial sensors, motor drives, and appliance subsystems.

For engineers reviewing the MC908GP16CBE datasheet, MC908GP16CBE pinout, MC908GP16CBE application, or MC908GP16CBE equivalent, this page delivers verified technical context, package mapping, functional specifications, and real-world use cases - all grounded in Freescale's official MC68HC908GP32 family documentation and mechanical data for the CBE variant.

Technical Context

The MC908GP16CBE implements the HCS08 CPU core with enhanced addressing modes and a 16-level hardware stack. Its Clock Generator Module (CGM) integrates a crystal oscillator and PLL-based frequency multiplication, enabling flexible clock sourcing from internal RC or external crystal (1–8 MHz).

Peripheral integration includes a 10-bit successive-approximation ADC with programmable sample time and conversion trigger sources, dual asynchronous serial interfaces (SCI and SPI), and a 16-bit Timer Interface Module (TIM) with input capture, output compare, and PWM generation capability - all mapped to dedicated I/O ports with configurable pull-ups and slew-rate control.

FAQ

What is the maximum operating frequency of the MC908GP16CBE?

The MC908GP16CBE supports a maximum bus frequency of 8 MHz, derived from its internal CGM with PLL multiplication. This frequency sets the timing boundary for instruction execution, ADC conversion rate, and peripheral module operation - all parameters are fully characterized in Freescale's MC68HC908GP32 datasheet Rev. 10, which applies directly to the MC908GP16CBE variant.

Does the MC908GP16CBE include an integrated ADC, and what are its key specs?

Yes, the MC908GP16CBE integrates a 10-bit successive-approximation ADC with 8 input channels (AD0–AD7 mapped to PTB0–PTB7). It supports software or hardware (TIM/SCI) triggers, programmable sample time, and reference selection between VDDAD and internal bandgap. Full electrical specs - including INL/DNL, offset/gain error, and conversion time - are documented in Chapter 4 of the MC68HC908GP32 datasheet.

What package type and pin count does the MC908GP16CBE use?

The MC908GP16CBE uses a 44-pin QFP (Quad Flat Package), case number 824A, with 0.8 mm lead pitch and 10 mm × 10 mm body dimensions. Its pinout matches the MC68HC908GP32 family, including dedicated VDD/VSS pairs, OSC1/OSC2, RST, and multiplexed I/O across Ports A–E - confirmed in Section 1.4 (Pin Assignments) and Section 1.5 (Pin Functions) of the official datasheet.

Can the MC908GP16CBE operate from a single 3.3 V supply?

Yes, the MC908GP16CBE operates over a supply range of 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V systems. All I/O pins are 5 V-tolerant when configured as inputs, and the internal voltage regulator supports stable core operation across this range - verified in Section 19 (Electrical Specifications) of the MC68HC908GP32 datasheet.

How is FLASH memory protected against accidental erasure in the MC908GP16CBE?

The MC908GP16CBE implements FLASH block protection via the FLASH Block Protect Register (FBPROT), allowing independent locking of any 512-byte block. Protection is enforced at the hardware level - write/erase commands to locked blocks are ignored. Configuration is performed through the FLASH Control Register (FCDIV/FCCOB) sequence, as detailed in Section 2.6.6 of the MC68HC908GP32 datasheet.
