Product details
Overview
MC908QY1CDTER from NXP Semiconductors (formerly Freescale) is an 8-bit M68HC08 core microcontroller designed for cost-sensitive, low-power embedded control applications. It features 1.5 KB on-chip FLASH, 128 bytes RAM, 8-channel 8-bit ADC, internal RC oscillator (4 MHz typical), and operates from 2.7–5.5 V. It is commonly used in appliance control panels, small motor drives, and sensor interface modules.
For engineers reviewing the MC908QY1CDTER datasheet, MC908QY1CDTER pinout, MC908QY1CDTER application, or MC908QY1CDTER equivalent, key selection criteria include its 16-pin SOIC package, integrated ADC with external reference support, COP watchdog, LVI reset protection, and compatibility with HC08 development tools and legacy code bases.
Technical Context
The MC908QY1CDTER implements the M68HC08 CPU core with 16-bit address space, supporting WAIT/STOP low-power modes and a programmable Computer Operating Properly (COP) watchdog timer with selectable timeout intervals. Its System Integration Module (SIM) manages clock generation, reset sources, and interrupt vectoring.
It integrates a 8-channel single-ended analog-to-digital converter with configurable sample time, conversion trigger options (software, timer, or external), and interrupt-on-complete capability. The internal RC oscillator supports trimming via OSCTRIM register to achieve ±2% accuracy across temperature and voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC908QY2CDTER | 2 KB FLASH, same pinout and peripheral set; higher memory for larger UI or protocol stacks | Preferred where bootloader, OTA update support, or expanded feature set requires >1.5 KB code space | Select when additional FLASH is needed without changing PCB layout or driver software |
| MC908QT1CDTER | Same FLASH/RAM, but lacks ADC; adds TCLK input for external timer synchronization | Suitable for pure digital control tasks (e.g., LED sequencers, relay timers) where analog sensing is unnecessary | Choose when ADC is unused and precise external timing alignment is required |

FAQ
What is the maximum operating frequency of the MC908QY1CDTER?
The MC908QY1CDTER supports a maximum bus clock frequency of 4 MHz when using the internal trimmed RC oscillator. With external crystal or clock source, the bus clock may reach up to 8 MHz depending on configuration and voltage - however, the device is fully specified and tested for reliable operation at 4 MHz across its full temperature and voltage range. The MC908QY1CDTER datasheet confirms this limit in Section 16 Electrical Specifications.
Does the MC908QY1CDTER support in-circuit programming?
Yes, the MC908QY1CDTER supports in-system programming (ISP) of its 1.5 KB FLASH memory via the MON (Monitor) module using a standard RS-232 interface and compatible debug adapter. Programming requires the MC908QY1CDTER to be held in monitor mode using the BKGD pin and a valid 6-byte entry sequence - no external programmer hardware is needed beyond a UART-level signal translator.
How many ADC channels does the MC908QY1CDTER have, and what is their resolution?
The MC908QY1CDTER integrates an 8-bit successive-approximation analog-to-digital converter with 8 single-ended input channels (AN0–AN7), mapped to Port A pins PTA0–PTA7. Each conversion completes in ≤25 µs with typical INL of ±1 LSB and no missing codes across the full operating range. The MC908QY1CDTER ADC supports both internal and external voltage reference configurations.
Is the MC908QY1CDTER pin-compatible with other QY/QT family members?
Yes, the MC908QY1CDTER shares identical pinout and package (16-pin SOIC) with MC908QY2CDTER, MC908QY4CDTER, MC908QT1CDTER, and MC908QT2CDTER. This allows direct substitution within the same footprint when memory, ADC, or oscillator requirements align - though firmware validation is required due to differences in FLASH size and peripheral enable bits.
What debug interfaces are supported by the MC908QY1CDTER?
The MC908QY1CDTER supports background debug mode (BDM) via the BKGD pin, enabling full read/write access to memory and registers, real-time breakpoint insertion, and single-stepping without halting peripherals. It also supports monitor mode via UART for FLASH programming and basic register inspection - both interfaces are documented in Chapter 15 of the MC68HC908QY/QT Family Data Sheet.
