Introduction
Zilog’s Z8 Encore! XP®F1680 Series microcontrollers (MCU) are based
on the 8-bit eZ8 CPU core and optimizedfor low-power applications. The
Z8 Encore! XP F1680 Series support 1.8 V to 3.6 V operation with
extremely low Active, Halt, and Stop mode currents and an assortment of
speed and low power options. Z8F1680AN020 is the silicon used in the
board. For more information, refer to Z8 Encore! XP®F1680 Series
Product Specification (PS0250). The features to balance power and per-
formance needs of applications include:
• Wide operating voltage range: 1.8 V–3.6 V.
• Active, Halt, and Stop operational modes with the ability to enable or
disable peripherals for power savings.
• Oscillator control that determines clock source, operating speed, and
fail safe operation in addition to fast wakeup.
• A user-controlled Program RAM area to store interrupt service
routines (ISR) of high-frequency interrupts. The Program RAM
mechanism ensures low average current and quick response for high-
frequency interrupts.
MCU Features
Features of the Z8 Encore! XP F1680 MCU include:
• Two Z8F1680AN020SG 44-pin Devices with 20 MHz eZ8 CPU core
• 16 KB Flash memory with in-circuit programming capability
• 2 KB register data RAM
• 1 KB Program RAM for program code shadowing and data storage
• 256 B non-volatile data storage (NVDS)

Hardware-Supported Software Features
Zilog’s eZ8 MCU, latest 8-bit MCU meets the continuing demand for
faster and more code-efficient microcontrollers. It executes a superset of
the original Z8®instruction set. The eZ8 MCU features include:
• Direct register-to-register architecture allows each register to function
as an accumulator, improving execution time and decreasing the
required Program Memory.
• Software stack allows greater depth in sub-routine calls and interrupts
more than hardware stacks.
• Compatible with existing Z8 code.
• Expanded internal Register File allows access up to 4 KB.
• New instructions improve execution efficiency for code developed
using higher-level programming languages including C.
• Pipelined instruction fetch and execution.
• New instructions for improved performance including BIT, BSWAP,
BTJ, CPC, LDC, LDCI, LEA, MULT, and SRL.
• New instructions support 12-bit linear addressing of the register file.
• Up to 10 MIPS operation.
• C-Compiler friendly.
• 2 to 9 clock cycles per instruction.
For more details on eZ8 MCU, refer to eZ8TM CPU User Manual
(UM0128),available for download at www.zilog.com.

• RS-232 interface.
• Two MDS connectors.
• I2C-driven DAC that provides analog input for the Z8F1680_S
device.
• The Slave device has a 20 MHz crystal; the Master device uses
internal IPO.
• On-chip debugger interface.
The module has two main modes of operation:
• Downloading and debugging code into the Slave device through the
Master device, using the connection of the OCD of the Slave device
to the UART1 of the Master device. In this case, PA7 of the Master
device is acting as a Reset source for the Slave device and needs to be
configured as an output with Open Drain.
• Downloading and debugging code in either the Master or Slave
device using the standard OCD interface on either chip.
The operation mode is selected by switch S2.
All the GPIOs of both devices, except for those used on the module are
connected to JP1 and JP2. All the GPIOs of the Slave device, except
analog inputs are connected to the odd pins of JP1. The GPIOs of the
Master device are connected to the even pins of JP1 and to JP2. All the
analog inputs of the Slave device are connected to JP2. Input PB3/ANA3
of the Slave device can be connected through J1 to either the output of U2
(12-bit DAC) or to JP2 pin 6.
The 12-bit DAC7571 manufactured by TI (U2) is controlled either by
Master or Slave device.
