MC68HC16Z1CEH16 - 16MHz CPU16 MCU 1K RAM ROMless 132-PQFP | NXP
MPN: MC68HC16Z1CEH16 ✗ Cuối đờiMC68HC16Z1CEH16 Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a processor, volatile memory (RAM), non-volatile memory (ROM/Flash), and configurable peripherals on one die. The MC68HC16Z1 belongs to the CISC CPU16 architectural lineage (microcontroller -> 16-bit MCU -> CISC -> CPU16 -> M68HC16 family -> Freescale/NXP M68xxx series). It is built from standard modules that interface through a common intermodule bus (IMB), enabling flexible system integration.
Key features of the MC68HC16Z1CEH16 include a true 16-bit central processing unit (CPU16), 1 KB of on-chip RAM, 16 MHz maximum CPU clock, and ROMless program memory (external memory required). The device supports 3.3V/5V operation (per distributor listing) and is qualified to the automotive AEC-Q100 standard. Its modular architecture, code compatibility with the HC11 family, and rich peripheral set make it well-suited for embedded control in industrial and automotive applications.
Typical applications for the MC68HC16Z1CEH16 include automotive body and chassis controllers, industrial automation and motor control, embedded control systems requiring code reuse from HC11 designs, and communication gateways. Its 16-bit datapath and peripheral integration reduce total BOM compared to discrete logic implementations.
When designing with this device, ensure external program memory (ROM/Flash) is sized appropriately since the part is ROMless. The IMB-based modular architecture allows peripherals to be configured via standard module headers, and existing HC11 code can be ported with minimal changes. Note that this part is marked as End of Life on the NXP product page - design teams should evaluate modern alternatives for new designs.

Ứng dụng tiêu biểu
MC68HC16Z1CEH16 phù hợp cho 6 Áp dụngs: Automotive Body and Chassis Control, Industrial Automation Controllers, Embedded Control with HC11 Code Reuse, Communication Gateways and Protocol Bridges, Motor Control and PWM Drive, Test and Measurement Instrumentation.
Automotive Body and Chassis Control
The MC68HC16Z1CEH16's 16-bit CPU16 core, 16 MHz throughput, and AEC-Q100 qualification make it well-suited for automotive body and chassis control modules such as body controllers, lighting controllers, and seat/window modules. Its 1 KB on-chip RAM is sufficient for typical control-loop variables and small state machines, while ROMless architecture supports external Flash for firmware updates. Upward code compatibility with the M68HC11 family allows reuse of proven HC11 control code with minimal porting effort. Compared to discrete 8-bit alternatives, the 16-bit datapath doubles arithmetic throughput for sensor fusion tasks.
Được đề xuất
Industrial Automation Controllers
For industrial automation, the MC68HC16Z1CEH16 delivers deterministic 16 MHz performance for PLC-style control loops, motor drives, and sensor interfaces. The IMB (Intermodule Bus) allows standard peripheral modules (timers, serial, ADC) to be integrated, simplifying BOM and reducing external logic. ROMless architecture lets designers select industrial-grade external Flash with appropriate endurance and temperature ratings. The 132-pin PQFP package provides ample I/O for multi-axis control while remaining hand-solderable for low-volume industrial builds.
Được đề xuất
Embedded Control with HC11 Code Reuse
Designers with existing M68HC11 firmware can port code directly to the MC68HC16Z1CEH16 thanks to its upward code compatibility with the HC11 family. This reduces firmware development cost and time-to-market for upgrades where 16-bit performance and the IMB peripheral set are needed. Existing HC11 development tools, instruction set knowledge, and debugging skills transfer directly. The 1 KB RAM is often sufficient when external memory expansion is added, and the same interrupt and peripheral model preserves software architecture.
Được đề xuất
Communication Gateways and Protocol Bridges
The MC68HC16Z1CEH16's 16-bit datapath and IMB-based peripheral integration support communication gateway applications such as CAN-to-UART bridges, industrial protocol converters, and sensor network hubs. Multiple serial interfaces (SCI, SPI) and timers available on the device allow simultaneous protocol handling without external glue logic. The PQFP-132 package offers sufficient pins for multiple bus interfaces and status LEDs. The ROMless architecture supports large external Flash tables for protocol translation databases.
Được đề xuất
Motor Control and PWM Drive
The MC68HC16Z1CEH16 includes timer modules suitable for multi-channel PWM generation required by BLDC, stepper, and DC motor control. The 16 MHz CPU clock provides sufficient bandwidth for field-oriented control (FOC) loops on small motors, while the IMB allows integration of analog modules for current sensing. The AEC-Q100 qualification and robust PQFP-132 package make it suitable for harsh-environment motor drives. Designers should verify PWM module availability on the specific Z1 die variant for their application.
Được đề xuất
Test and Measurement Instrumentation
For test and measurement equipment, the MC68HC16Z1CEH16 offers 16-bit processing power for data acquisition front-ends, signal conditioning controllers, and instrument user-interface controllers. Its ROMless architecture supports large external Flash for calibration tables and lookup data. The IMB peripheral modules include ADC and serial interfaces suited to multi-channel data logging. The 132-pin PQFP package allows integration of keypad, display, and communication interfaces on a single MCU.

Ghi chú thiết kế
The MC68HC16Z1CEH16 is marked End of Life by NXP (per https://www.nxp.com/part/MC68HC16Z1CEH16). New designs should not start on this part. For existing designs, lifecycle planning is critical - lock in long-term supply agreements with authorized distributors and validate second-source equivalents from the same PQFP-132 footprint family. Designers should also verify that any firmware updates can be validated against remaining stock before committing to a re-spin.
The MC68HC16Z1CEH16 supports both 3.3V and 5V operation. Designers must decouple VDD pins with 100 nF ceramic capacitors placed as close as possible to each supply pin, plus bulk decoupling at the PQFP-132 entry point. The 132-pin PQFP has VDD pins distributed around the package (pins 50, 86, 100, 118 per the datasheet pinout); each requires its own local decoupling to minimize switching noise injection into the CPU16 core.
The 132-pin PQFP package has leads on all four sides at 24.13 mm body size. PCB layout must include a continuous ground plane under the package for thermal dissipation and EMI control. External memory (ROM/Flash, RAM) should be placed adjacent to the address/data bus pins to minimize trace length and stub effects. Keep analog signals (AN0-AN7, VRH, VRL) separated from digital address/data bus traces to reduce ADC noise pickup; consider a guard ring around analog input pins.
Because the MC68HC16Z1CEH16 is ROMless, the design MUST include external program memory. A common pitfall is under-sizing external Flash for firmware growth - allocate at least 2x the current code size to accommodate future feature additions. Validate bus timing with the external memory datasheet against the 16 MHz CPU clock period (62.5 ns) and the IMB wait-state configuration. Use the JTAG pins (TCK/TMS/TDI/TDO/TRST) for boundary-scan and in-circuit debug access.
