MC908QY1CDTER Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/FLASH), data memory (RAM), and a range of peripheral I/O into one package. The HC08 is NXP/Freescale's 8-bit CISC architecture targeted at cost-sensitive embedded applications where deterministic behavior, low power, and compact code density matter more than raw throughput. Within the broader taxonomy, the MC908QY1CDTER is a member of the HC08Q sub-family, sitting below higher-tier 16-bit and 32-bit MCUs but above simple logic controllers in capability.
Key features of the MC908QY1CDTER include 1.5KB of in-system programmable FLASH, 128 bytes of RAM, 14 general-purpose I/O pins, an internal 32 MHz oscillator (with a 5V-tolerant bus interface), and a 5V (4.5V to 5.5V) supply range. The TSSOP-16 footprint provides a slim 4.40 mm body width suitable for space-constrained PCB layouts common in white goods, sensor interfaces, and low-end appliance controllers. As an NXP "Nitron" HC08 device, it is designed for low-power, low-noise analog-friendly embedded designs.
Architecturally, the MC908QY1CDTER uses the M68HC08 enhanced CPU core with BDM (Background Debug Mode) for in-circuit programming and debugging. The device supports a wide supply tolerance to accommodate regulated 5V rails and offers mask-ROM/FLASH variants within the same pinout for OEM cost-down paths. Common peripherals shared across the QY series include timers, an SCI (serial communications interface), and basic input-capture/output-compare channels.
Typical applications are low-cost consumer appliances, battery chargers, industrial sensor signal conditioning front-ends, simple motor-control loop controllers, and replacement of legacy HC05/HC11 designs. The 5V supply tolerance suits automotive subsystems operating at 5V nominal, low-end industrial controllers, and hobby electronics.
When designing with this MCU, ensure the decoupling capacitor is placed as close as possible to the VDD/VSS pair and use the BDM interface for FLASH programming rather than legacy monitor-mode code. The 16-TSSOP package offers a 0.65 mm pin pitch; consider solder joint inspection and stencil aperture tuning during PCB assembly.

Typische Anwendungen
MC908QY1CDTER ist geeignet für 7 Anwendungs: Consumer Appliance Controller (Washing Machine / Dishwasher Front Panel), Industrial Sensor Signal-Conditioning Front-End, Battery Charger State-Machine Controller, White-Goods LED Status Indicator Driver, Automotive 5 V Subsystem Controller (Non-Safety Domain), Consumer Remote-Control and IR-Transmitter MCU, Industrial Point-of-Sale / Barcode Wand Decoder.
Consumer Appliance Controller (Washing Machine / Dishwasher Front Panel)
The NXP MC908QY1CDTER fits low-cost consumer appliance controllers where its 1.5 KB FLASH holds a stable-state UI routine, 14 I/O pins drive an LED array plus keypad matrix, and the 5 V supply matches legacy analog front-ends. Placed on a button-pad PCB with a regulator-fed 5 V rail, it replaces HC11 designs while keeping the legacy toolchain - the BDM debug pin allows factory firmware calibration. Compared to a CPLD, the HC08 integrates CPU and I/O in one chip, reducing BOM count by 3-4 parts. Its -40 C to +85 C industrial temperature range suits garage-free kitchen environments. The TSSOP-16 saves 30% board area versus SOIC-16, enabling slimmer keypad sub-PCBs.

Industrial Sensor Signal-Conditioning Front-End
Industrial sensor interface boards use the MC908QY1CDTER to read thermocouple / RTD signals, debounce limit switches, and route a UART line to the main PLC. Its 14 I/O pins handle up to seven differential-style switch channels plus a half-duplex serial link to the upstream controller. The 4.5-5.5 V tolerance accommodates 24 V industrial rails stepped down by a small switching regulator. The HC08 CISC core runs deterministic loop timing critical for safety chains - 125 ns bus cycles make precise debounce windows repeatable. Built around an external SPI ADC such as the MCP3201, the design totals $1.30 BOM in volume. Industrial temperature grade (-40 C to +85 C) handles factory floor thermal swings.
Empfohlen
Battery Charger State-Machine Controller
Lead-acid or NiMH charger front-ends pair the MC908QY1CDTER with a discrete PWM/MOSFET stage to run a charge-state engine encoded in 1.5 KB of FLASH. The HC08 reads battery voltage via resistor-divider on an I/O pin and toggles charge enable from a control FET. Critical timing (charge cycle period, voltage sampling window) is handled in cheap MCU instructions rather than expensive analog timers. Its 5 V supply and -40 C to +85 C industrial range accommodate garage or outdoor charging stations. Compared to a fully analog charger, the MCU version is firmware-tunable, allowing OEMs to ship one hardware platform for multiple chemistries.

White-Goods LED Status Indicator Driver
Refrigerator door ajar, dishwasher cycle, and dryer status LEDs are cheap to drive using the MC908QY1CDTER's 14 I/O pins as direct current-controlled outputs. The MCU generates blink patterns, plays audio feedback (via tone output PWM), and listens to door-switch inputs - all within a single 16-TSSOP footprint. The 5 V supply accepts a small buck regulator output with headroom margin, while the HC08's near-instantaneous wake-up from STOP mode allows sub-100 uA standby, meeting EU standby power rules. Replacing a dedicated LED-driver IC with the MC908QY1CDTER cuts the bill of materials by $0.30 to $0.50 per board.

Automotive 5 V Subsystem Controller (Non-Safety Domain)
Body controllers for seat adjusters, mirror modules, and accessory multiplex use MC908QY1CDTER-class 8-bit MCUs where determinism and cost outweigh raw throughput. The 5 V supply matches 5 V-rail automotive subsystems, and -40 C to +85 C covers cabin thermal loads (engine bay needs AEC-Q100 Kinetis parts). The HC08 in this design communicates over CAN or LIN bus to a master ECU using a transceiver such as the NXP TJA1050. BDM in-circuit programming speeds OEM factory calibration. Compared to discrete 555-timer-based controllers, the MC908QY1CDTER delivers firmware-tunable behavior without PCB respins.
Empfohlen
Consumer Remote-Control and IR-Transmitter MCU
Low-end IR remote controls for TVs, set-top boxes, and AC units traditionally use mask-ROM 4-bit controllers; modern designs swap them for the MC908QY1CDTER which costs about the same, ships in FLASH, and enables rapid OEM customization. The HC08 emits NEC or RC-5 IR protocols through bit-banged GPIOs, debounces the keypad matrix in software, and sleeps at sub-100 uA between key presses. Three AAA cells (4.5 V) sit directly on its supply rails without regulation. The TSSOP-16 footprint fits slim remotes where SOIC-16 would not. Compared to off-the-shelf encoders, this approach is fully programmable.

Industrial Point-of-Sale / Barcode Wand Decoder
Low-cost barcode scanner wands and POS terminals deploy the MC908QY1CDTER to decode pulse streams from photodiode amplifier circuits and drive a UART link to a host display or PC. The HC08's fast interrupt response (under 50 instruction cycles for an IRQ entry) handles real-time edge-to-edge timing needed to discriminate UPC/EAN stripe patterns. The 5 V supply runs directly from a USB-to-5V LDO, and the 16-TSSOP footprint drops into thin, foldable scanner enclosures. Compared to a fully hardware decoder, this MCU version adapts to evolving barcode standards via firmware updates and adds diagnostic logging free of charge.

Designhinweise
The MC908QY1CDTER requires a regulated 4.5 V to 5.5 V supply. Place a 100 nF decoupling capacitor as close as possible to the VDD/VSS pins (typical < 5 mm trace length) to suppress switching noise from internal oscillators. For multi-rail designs, add a 10 uF tantalum or ceramic bulk capacitor near the part to handle transient current spikes during FLASH programming, where peak current can briefly exceed 30 mA. If a 3.3 V rail is the only source available, step up to 5 V with a small switching regulator before the MCU - the HC08 lacks low-voltage tolerance. Estimated: 30 mA peak at 5 V for BDM erase operations, sustained ~10 mA active.
On the TSSOP-16 board, keep the OSC1/OSC2 traces short and symmetric, shield them from high-current I/O paths, and add a ground guard trace to reduce jitter. The 0.65 mm pin pitch of TSSOP-16 demands PCB solder-mask apertures with maximum 0.45 mm diameter openings to prevent solder bridging; use 0.1 mm pad-to-trace clearance. Star-route VSS from the decoupling capacitor directly to the bypass ground and then to the PCB ground plane; do not daisy-chain VSS across the package. Pin 1 (PTA0/IRQ) is the primary interrupt and should be routed with 5 ns propagation budget.
Ensure the IRA pin (shared with PTA0) is configured correctly - on reset it defaults to IRQ input with internal pull-up disabled. Without external pull-up, a floating IRQ pin can trigger spurious interrupts that disrupt timing-sensitive code. Avoid relying on the 32 MHz internal oscillator for applications requiring high UART accuracy; use the BUSCLK divided output to the SCI block. The VDD rise time during power-up must meet datasheet specification; an RC rise > 100 ms can fail the internal reset circuit. BDM programming requires the BDM pin held low at reset, so design a mini-header that exposes VDD, VSS, BDM, and RESET.
When using the SCI block for UART communication with receivers above 1 Mbps, route the TX/RX traces as a short differential pair with characteristic impedance 50 ohms (typical for USB or RS-232 single-ended signals) and add a 100-ohm series termination resistor near the MCU. The HC08's SCI block generates ~25 ns overshoot on bus transitions; if the cable length exceeds 30 cm, add an external 5 kV-rated ESD diode array such as the NXP PESD5V0L4UG on the line side. Maintain VSS noise below 50 mV peak by pairing each VDD with a high-frequency bypass cap.
