MC68HC16Z1CAG16 Обзор

The NXP MC68HC16Z1CAG16 is a 16-bit ROMless microcontroller from the M68HC16 family, built on the CPU16 core and operating at 16 MHz, housed in a 144-pin LQFP package (20x20 mm). The device is upwardly code-compatible with the long-established M68HC11 8-bit family, allowing existing firmware to migrate with minimal effort while gaining 16-bit data paths and addresses.

An M68HC16 microcontroller is a high-speed 16-bit control unit that combines high-performance data manipulation capabilities with powerful peripheral subsystems. It belongs to the M68HC16 Family of modular microcontrollers, where it sits in the broader taxonomy of: microcontroller -> 16-bit MCU -> M68K-derived core -> CPU16 architecture -> automotive/industrial control. The architecture uses standard modules that interface through a common intermodule bus (IMB), enabling flexible peripheral integration. Compared with the older 68HC11, the 68HC16Z1 doubles address space, supports 16-bit arithmetic natively, and adds larger on-chip RAM while keeping the same instruction-set philosophy.

Key features of the MC68HC16Z1CAG16 include: 16 MHz CPU16 core at 16 MHz, 1 KB of on-chip RAM, 16 programmable I/O lines, ROMless program memory, and three communication buses (EBI/EMI external bus interface, SCI serial communications interface, and SPI serial peripheral interface). On-chip peripherals include a programmable timer with PWM, a watchdog timer, and a power-on reset block. The 144-LQFP package supplies the I/O count required for external memory plus parallel peripherals in industrial control systems.

The CPU16 implementation uses a 16-bit native datapath with 16-bit internal registers and 24-bit addressing via segmented memory. The modular IMB bus decouples core upgrades from peripheral development - the same CPU16 core is reused across the Z1/Z2/Z3/Z4 family with different peripherals. The result is a controller that runs standard 68HC11 C/assembly code recompiled, while taking advantage of the integrated EBI for external SRAM/Flash expansion.

Typical applications include automotive body controllers, industrial PLC modules, motor-control edge nodes, instrumentation front-ends, and any 16-bit migration path from legacy 68HC11 designs. The combination of SCI for fieldbus bridges, SPI for sensor hubs, and EBI for external memory suits robust factory-floor designs. Because it is ROMless, designers can pair the MCU with a boot ROM, NOR Flash, or external EEPROM to implement application-specific firmware.

When designing with the MC68HC16Z1CAG16, observe that this part is marked Discontinuance and Replacement per NXP product page, so long-term designs should plan for an upgrade path. Ensure decoupling caps are placed within 5 mm of each VDD/VSS pair, and that the IMB clock is sourced from the on-chip PLL or an external crystal as documented. Length-matching is recommended for the EBI address/data bus when external memory is added at full 16 MHz operation.

This page synthesizes distributor stock, drop-in alternatives from the M68HC16 family, lead-time references, and practical design notes not collected in the manufacturer datasheet itself, giving engineers a single reference point for sourcing and selecting this legacy 16-bit MCU.

Типичное применение

MC68HC16Z1CAG16 подходит для 6 применениеs: Automotive Body Control Module, Industrial PLC Module, Motor Control Edge Node, Medical Instrumentation Front-End, Factory Sensor Hub / SPI Bridge, Test and Measurement Instrumentation.

🚗

Automotive Body Control Module

The MC68HC16Z1CAG16's 16 MHz CPU16 core and code-compatible M68HC11 heritage made it a 1990s-era staple for body-control ECUs. With 16 I/O lines, EBI for external memory, and an SCI port for LIN/K-Line datalinks, designers wire it to drive lamp drivers, door modules, and climate-control panels. The choice of ROMless program memory allowed tier-1 suppliers to mask-ROM application code per vehicle platform while reusing the same silicon. For 2026 maintenance design, plan migration to active S12/S12X parts.

🏭

Industrial PLC Module

Industrial PLC front-end modules benefit from the MC68HC16Z1CAG16 combination of a 16-bit datapath, EBI for fast SRAM/ROM expansion, and SCI for RS-232/RS-485 fieldbus. The CPU16 core at 16 MHz handles ladder-logic scanning and PID loops while the watchdog timer ensures safe-state recovery on firmware faults. The 144-LQFP footprint provides ample I/O for digital-input conditioning on a single chip, and the modular IMB bus eases peripheral reuse across the Z-series.

⚡

Motor Control Edge Node

Variable-frequency drive edge nodes harness the MC68HC16Z1CAG16 PWM timer, EBI for IGBT gate-driver interfaces, and SCI for CAN-bridge or RS-485 commissioning. The 16-bit datapath delivers precise duty-cycle computation and SVPWM modulation, while the SPI port reaches ADC and resolver chips for current/position feedback. Designers appreciate the 5V-tolerant I/O and the wide industrial operating range typical of M68HC16 parts. Modern equivalents use the S12ZVFP for cleaner BOM.

💊

Medical Instrumentation Front-End

Bedside patient-monitor front-ends historically pair a 16-bit CPU with a precision ADC, and the MC68HC16Z1CAG16 fits through its SPI to ADC bridges, SCI to host computer link, and EBI to memory-mapped display buffers. The ROMless architecture allows medical OEMs to comply with FDA traceability via a unique firmware build per instrument. The 144-LQFP package gives enough GPIO for keypad, alarm, and LCD bias. New medical designs should default to active-portfolio ARM Cortex-M parts.

🧩

Factory Sensor Hub / SPI Bridge

Industrial sensor hubs aggregate analog and digital sensors through SPI and SCI buses, and the MC68HC16Z1CAG16's SPI port plus SCI port and 16-bit GPIO lines enable hub designs that front-end MEMS accelerometers, temperature arrays, and digital pressure sensors. The CPU16 core handles MODBUS RTU encoding on the SCI while forwarding SPI telemetry to a higher-tier controller. The ROMless firmware approach simplifies OEM-specific calibration.

📺

Test and Measurement Instrumentation

Bench instruments such as data loggers and protocol analyzers use the MC68HC16Z1CAG16 to capture serial traffic and buffer it to external memory, leveraging the EBI's wide address reach and the SCI/SPI ports for multi-protocol ingest. The CPU16's 16-bit datapath accelerates FFT pre-processing and statistics accumulation in firmware. ROMless program memory enables last-minute protocol decoder updates in production.

The MC68HC16Z1CAG16 is a 16-bit ROMless microcontroller from NXP Semiconductors (formerly Freescale/Motorola), built on the CPU16 core and housed in a 144-LQFP package (20x20 mm). It operates at 16 MHz, includes 1 KB of on-chip RAM, 16 programmable I/O lines, and integrates EBI/EMI, SCI, and SPI connectivity, making it suitable for industrial control and automotive body modules.
Is the MC68HC16Z1CAG16 still in production?
No, the MC68HC16Z1CAG16 is shown as Discontinuance and Replacement on the NXP product page and is generally considered End of Life by 2026-10-21. Distributors such as DigiKey and Mouser may still list limited stock, but new production has been wound down, so engineers should plan a migration path to the S08, S12, or S12X families.
What is the program memory of MC68HC16Z1CAG16?
The MC68HC16Z1CAG16 has ROMless program memory, meaning there is no internal Flash or mask-ROM. Applications must boot from external ROM or NOR Flash via the External Bus Interface (EBI) at the address space mapped by the CPU16 24-bit segment. This was a common architecture for production lines that needed mask-programmable memory in 1990s-era automotive designs.
How much RAM does MC68HC16Z1CAG16 have?
The MC68HC16Z1CAG16 integrates 1 KB of on-chip RAM. According to the Freescale datasheet (17 MHz Electrical Characteristics, 28 pages), the RAM is organized as a single block on the internal module bus (IMB) and is suitable for stack and data storage, while large buffers must reside in external memory accessed through the EBI.
What peripherals does MC68HC16Z1CAG16 integrate?
The MC68HC16Z1CAG16 integrates a Power-On Reset (POR) block, a PWM-capable timer, a Watchdog Timer (WDT), and three communication channels: EBI/EMI external bus, SCI serial communications interface, and SPI serial peripheral interface. These modules share an internal Inter-Module Bus (IMB), the standard M68HC16 backplane used across the Z1/Z2/Z3/Z4 family.
Is MC68HC16Z1CAG16 code-compatible with 68HC11?
Yes, the M68HC16 Z-series including the HC16Z1 is upwardly code-compatible with M68HC11 controllers. According to the Freescale data sheet, 68HC11 source can be recompiled to run on the CPU16 16-bit core with minimal changes, primarily addressing segment registers and extended addressing modes, which made the family a popular industrial migration path.
What package is the MC68HC16Z1CAG16 in?
The MC68HC16Z1CAG16 is shipped in a 144-LQFP plastic package measuring 20x20 mm with a 0.5 mm pitch. The 144-LQFP provides the high I/O count required to expose the External Bus Interface address and data lines, plus dedicated SCI, SPI, timer, and GPIO pins for industrial control designs.
Where can I download the MC68HC16Z1CAG16 datasheet PDF?
The MC68HC16Z1CAG16 datasheet is hosted on AllDatasheet and Datasheet Bank, with the Freescale/NXP publication titled M68HC16Z Series datasheet covering 17 MHz electrical characteristics. The Alldatasheet URL listed in the data_sources field is the primary PDF download, and the NXP product page links to the same document set.
Where to buy MC68HC16Z1CAG16 online?
As of 2026-10-21, the MC68HC16Z1CAG16 can be purchased from DigiKey (page 968319) and Mouser, both of which list the part with shipping options. Octopart aggregates pricing from 3 distributors for the MC68HC16Z1CAG16, useful for comparing unit-pricing tiers and lead times, but expect inventory to be limited since the part is on the NXP Discontinuance list.
What is the lead time for MC68HC16Z1CAG16?
Lead time for the MC68HC16Z1CAG16 is typically noted as ships today or short stock from authorized distributors on 2026-10-21, but quantities beyond remaining distributor allocation are not new production. Customers should treat the lead time as finite and qualify a long-term replacement from the M68HC16 Z-series or the Freescale S12 family before design freeze.
What is the price of MC68HC16Z1CAG16?
As of 2026-10-21, the MC68HC16Z1CAG16 unit price ranges approximately USD 28.50 at qty 1 down to USD 15.95 at qty 1000 based on aggregated distributor tiers. Pricing exceeds the original mid-1990s MSRP due to last-time-buy scarcity and limited remaining stock at authorized distributors.
What is the best drop-in replacement for MC68HC16Z1CAG16?
The best drop-in replacement for the MC68HC16Z1CAG16 in the same 144-LQFP family package is the MC68HC16Z1MAG16 from NXP (memory and supply variant, same die, same 144-LQFP footprint), followed by the MC68CK16Z1CAG16 (added cryptographic module, same package). For modern production designs requiring active supply, migrate to the S12X family (for example the S912XDT384J1MAG) which uses a similar peripheral philosophy.
MC68HC16Z1CAG16 vs MC9S12H256VFVE - which is better for new designs?
For new designs, the NXP MC9S12H256VFVE is the better choice because it has 256 KB of internal Flash, a richer peripheral set, and is active in NXP's product portfolio as of 2026-10-21. The MC68HC16Z1CAG16 is ROMless and on the Discontinuance list, so while it offers pin-compatible IMB philosophy, only choose it for legacy maintenance. For migration projects prefer the HCS12 family.
Can the MC9S12HZ256CPV replace the MC68HC16Z1CAG16 directly?
Yes, the NXP MC9S12HZ256CPV is a recommended replacement candidate that exists in the same M68HC lineage, although you must verify board pinout: this part is a 144-LQFP-compatible S12 with on-chip Flash and a richer peripheral set, but it does not retain the exact 68HC16Z1 pinout at every ball/lead, so PCB rework is generally required for true drop-in upgrade.
Is the MC68HC16Z1CAG16 suitable for industrial PLC applications?
Yes, the MC68HC16Z1CAG16 is well-suited to industrial PLC and module applications because it integrates an EBI for external memory expansion, an SCI for fieldbus bridges (RS-232/RS-485), an SPI for sensor hubs, and a watchdog timer for safety-critical firmware. The CPU16 core at 16 MHz provides deterministic 16-bit control arithmetic; however, for new PLC designs prefer the active-production NXP S12X or Kinetis families.

Справочные инженерные данные для MC68HC16Z1CAG16 — сравнение, рекомендации по проектированию и информация о соответствии.

Руководство по выбору

Choose the MC68HC16Z1CAG16 when supporting legacy M68HC11 firmware migrations that need a 16-bit datapath within the 144-LQFP footprint, and when the design requires an EBI for external boot ROM/NOR Flash expansion. For new industrial designs prefer the S12X or S12Z families that integrate Flash and Ethernet, since the MC68HC16Z1CAG16 is on NXP's Discontinuance and Replacement list as of 2026-10-21. Pick MC68HC16Z1MAG16 for the same 16 MHz grade with extended memory mapping, or MC68HC16Z2CAG16 when additional peripheral modules (more timers, larger RAM up to 2 KB) are needed. All five drop-in alternatives share the 144-LQFP footprint, simplifying PCB reuse across the Z-series during long-life maintenance windows.

Ключевые отличия

  • M68HC11 upward code-compatibility within 144-LQFP pinout (против MC68HC11F1CPU4)
  • Higher speed and on-chip memory in same M68HC16 Z-series package (против MC68HC16Z1CAG25)
  • Internal EBI for external Flash/RAM expansion (против MC9S12H256VFVE)

Заметки по проектированию

Estimated supply current for the MC68HC16Z1CAG16 operating at 16 MHz with all peripherals active is approximately 50-80 mA from a 5 V rail, plus I/O drive into loaded pins. Place 100 nF ceramic decoupling capacitors within 5 mm of each VDD/VSS pair and a bulk 10 uF tantalum at the board entry point. The POR block resets cleanly only when VDD rises monotonically above the specified minimum - use a supervisor or follow the Freescale application note for power-rail ramp.

The 144-LQFP requires length matching on the EBI address and data bus at full 16 MHz operation. Keep bus traces under 50 mm total length on the inner layers, and use matched impedance (typically 50 ohms) for traces longer than 25 mm. Place external memory devices adjacent to the EBI port pins to minimize stub lengths. For prototype work, follow the M68HC16Z-series reference design from the Freescale evaluation board manual.

Do not assume the ROMless boot mode begins execution at 0x000000 unconditionally - the CPU16 reset vector and chip-select configuration depend on the external memory map and bootloader. Read the boot-mode section of the Freescale datasheet before designing the address decoding. Also note that since the part is on the NXP Discontinuance list, qualify a replacement from the HCS12 or S12X families (for example S912XDT384J1MAG or MC9S12HZ256CPV) before design freeze to avoid future retooling.

Estimated junction temperature for the MC68HC16Z1CAG16 at full 16 MHz with all ports switching: P_D ~0.4 W typical. With R_thetaJA of approximately 50 C/W for the 144-LQFP on a JEDEC 2S2P test board, junction rise is roughly 20 C above ambient, leaving comfortable margin to the 125 C junction limit. For sealed enclosures, verify with derating curves in the Freescale datasheet.
