Z16F Series Flash Microcontroller
A 16-bit Single-Cycle CISC MCU Solution
Overview
From the company that brought you the revolutionary Z80
®
comes the future of 16-bit processing - the ZNEO
Z16F Series Flash Microcontroller. Zilog’s ZNEO Z16F is a powerful 16-bit CISC microcontroller that outper-
forms most RISC microcontrollers in its class. The ZNEO Z16F boasts a unique architecture that provides the
power, punch, and performance of a 32-bit, with the code, current efficiency, and cost of a 16-bit. The ZNEO
Z16F CPU boasts a highly optimized instruction set that achieves higher performance per clock cycle, with
less code space and lower overhead than competing architectures.
This powerful, yet simple core with sixteen 32-bit general-purpose registers supports complex CISC address-
ing modes and a single-cycle instruction set that includes frame pointer support, multi-bit shift, and multi-reg-
ister push/pop, as well as performance enhancing instructions such as Link and Unlink for lowering overhead.
Powerful signed and unsigned math operations include 32x32 multiply and 64/32 divide operations.
A rich array of intelligent peripherals and analog features make this microcontroller suitable for a large number
of applications, including security panels, industrial controls and motor control, including AC Induction and
Brushless DC motors.

Zilog’s ZNEO Z16F CPU meets the continuing demand for faster and more code-efficient microcontrollers.
The ZNEO Z16F CPU features are as follows:
• Pipelined architecture: Fetch, Decode, and Execute
• 16 MB of Program memory address space for object code and data with 8- or 16-bit data paths
• 8-, 16-, and 32-bit ALU operations
• 24-bit stack with overflow protection
• Direct register-to-register architecture allows each memory address to function as an
accumulator. This improves execution time and decreases the required program memory
• New instructions improve execution efficiency for code developed using higher-level
programming languages including ‘C’
For more information on the core architecture, please refer to the ZNEO Z16F CPU User Manual (UM0188)

chip flash memory
The products in the ZNEO Z16F Series feature up to 128 KB of non-volatile Flash memory with read/write/
erase capability. The Flash memory is programmed and erased in-circuit by either user code or through the
On-Chip Debugger (OCD). The Flash memory array is arranged in 2 KB pages. The 2 KB page is the mini-
mum Flash block size that is erased. The Flash memory is also divided into eight sectors, which is protected
from programming and erase operations on a per sector basis.
analog peripherals
The ZNEO Z16F Series devices include a 12-channel ADC. The ADC converts an analog input signal to a
10-bit binary number. The features of the successive approximation ADC include:
• 12 analog input sources multiplexed with GPIO ports.
• 2.5 μs conversion time
• Automatic Time-Tag of results
• Programmable timing controls
The ZNEO Z16F devices feature a general-purpose comparator and an operational amplifier.
• Moderate speed comparator (200 ns propagation delay) with a maximum input offset of 5 mV
• Two-input, one-output operational amplifier with a typical open loop gain of 10,000 (80 dB)
communication peripherals
The ZNEO Z16F devices feature a rich array of communication peripherals, including:
• 2 UARTs
- LIN Master/Slave
- IrDA Encoder/Decoder
- Multiprocessor 9-bit Mode
• Enhanced SPI (ESPI)
• I

to memory, or peripherals to peripherals. The features of DMA controller include:
• Four independent DMA channels
• Supports Internal and External Memory
• Direct and Linked List Modes
• Round-Robin Channel Priority
• Byte, word, or quad operation, up to 64K transfers (64 KByte, 64 KWord or 64 KQuad)
• Shared bandwidth ZNEO Core
flexible interrupt control
The ZNEO Z16F Series includes offers interrupt control flexibility including:
• 8 External Rising or Falling Edge
• 4 External Dual Edge
• Vectored or Polled Interrupts
• 24 Interrupts with 3 Programmable Priority Levels
internal precision oscillator
The ZNEO Z16F incorporates a fully integrated Internal Precision Oscillator (IPO) that eliminates the need for
external components. With nominal untrimmed accuracy of ±30%., and the ability to manually trim the oscillator
to achieve a ±4% frequency accuracy over the operating temperature and supply voltage range of the device,
the ZNEO Z16F provides a best-in-class IPO feature set, including:
• On-chip RC oscillator which does not require external components
• Nominal ±30% accuracy without trim or manually trim the oscillator to achieve a ± 4%
• Typical output frequency of 5.5296 MHz or 32 kHz
• Trimming possible through Flash option bits with user override
• Eliminates crystals/ceramic resonators in applications where high timing accuracy is not required
