Functional Overview
The enCoRe V family of devices are designed to replace multiple
traditional full speed USB microcontroller system components
with one, low cost single-chip programmable component.
Communication peripherals (I2C/SPI), a fast CPU, Flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.
The architecture for this device family, as illustrated in the
“enCoRe V Block Diagram” on page 1, consists of two main
areas: the CPU core and the system resources. Depending on
the enCoRe V package, up to 36 general purpose I/O (GPIO) are
also included.
This product is an enhanced version of Cypress’s successful full
speed USB peripheral controllers. Enhancements include faster
CPU at lower voltage operation, lower current consumption,
twice the RAM and Flash, hot-swappable I/Os, I2C hardware
address recognition, new very low current sleep mode, and new
package options.
The enCoRe V Core
The enCoRe V Core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO
(internal main oscillator) and ILO (internal low speed oscillator).
The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a four-MIPS, 8-bit Harvard
architecture microprocessor.
System resources provide additional capability, such as a configurable I2C slave and SPI master-slave communication interface
and various system resets supported by the M8C.
Additional System Resources
System resources, some of which have been previously listed,
provide additional capability useful to complete systems.
Additional resources include low voltage detection and power on
reset. The following statements describe the merits of each
system resource.
■
■
Full speed USB (12 Mbps) with nine configurable endpoints
and 512 bytes of dedicated USB RAM. No external components
are required except two series resistors. It is specified for
commercial temperature USB operation. For reliable USB
operation, ensure the supply voltage is between 4.35V and
5.25V, or around 3.3V.
8 bit on-chip ADC shared between system performance
manager (used to calculate parameters based on temperature
for flash write operations) and the user.
2
■ The I C slave and SPI master-slave module provides 50, 100,
or 400 kHz communication over two wires. SPI communication
over three or four wires runs at speeds of 46.9 kHz to 3 MHz
(lower for a slower system clock).
■
2
In I C slave mode, the hardware address recognition feature
reduces the already low power consumption by eliminating the
Document Number: 001-12394 Rev *G
need for CPU intervention until a packet addressed to the target
device is received.
■
Low Voltage Detection (LVD) interrupts can signal the application of falling voltage levels, while the advanced POR (power
on reset) circuit eliminates the need for a system supervisor.
■
The 5V maximum input, 1.8, 2.5, or 3V selectable output, low
dropout regulator (LDO) provides regulation for I/Os. A register
controlled bypass mode enables the user to disable the LDO.
■
Standard Cypress PSoC IDE tools are available for debugging
the enCoRe V family of parts.

Development Tools
PSoC Designer™ is a Microsoft® Windows-based, integrated
development environment for the enCoRe and PSoC devices.
The PSoC Designer IDE and application runs on Windows XP
and Windows Vista.
This system provides design database management by project,
an integrated debugger with In-Circuit Emulator, in-system
programming support, and built-in support for third-party assemblers and C compilers.
PSoC Designer also supports C language compilers developed
specifically for the devices in the enCoRe and PSoC families.
PSoC Designer Software Subsystems
Chip-Level View
The chip-level view is a traditional integrated development
environment (IDE) based on PSoC Designer 4.4. You choose a
base device to work with and then select different onboard
analog and digital components called user modules that use the
PSoC blocks. Examples of user modules are ADCs, DACs,
Amplifiers, and Filters. You configure the user modules for your
chosen application and connect them to each other and to the
proper pins. Then you generate your project. This prepopulates
your project with APIs and libraries that you can use to program
your application.
The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration
allows for changing configurations at run time.
System-Level View
The system-level view is a drag-and-drop visual embedded
system design environment based on PSoC Designer.
Hybrid Designs
You can begin in the system-level view, allow it to choose and
configure your user modules, routing, and generate code, then
switch to the chip-level view to gain complete control over
on-chip resources. All views of the project share common code
editor, builder, and common debug, emulation, and programming
tools.
Code Generation Tools
PSoC Designer supports multiple third-party C compilers and
assemblers. The code generation tools work seamlessly within
the PSoC Designer interface and have been tested with a full
range of debugging tools. The choice is yours.
Document Number: 001-12394 Rev *G
Assemblers. The assemblers allow assembly code to be
merged seamlessly with C code. Link libraries automatically use
absolute addressing or are compiled in relative mode, and linked
with other software modules to get absolute addressing.
C Language Compilers. C language compilers are available
that support the enCoRe and PSoC families of devices. The
products enable you to create complete C programs for the
PSoC family devices.
The optimizing C compilers provide all the features of C tailored
to the PSoC architecture. They come complete with embedded
libraries providing port and bus operations, standard keypad and
display support, and extended math functionality.
Debugger
PSoC Designer has a debug environment that provides
hardware in-circuit emulation, allowing you to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow the designer to read and
program flash, read and write data memory, read and write I/O
registers, read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The
debugger also allows the designer to create a trace buffer of
registers and memory locations of interest.
Online Help System
The online help system displays online, context-sensitive help
for the user. Designed for procedural help and quick reference,
each functional subsystem has its own context-sensitive help.
This system also provides tutorials and links to FAQs and an
Online Support Forum to aid the designer in getting started.
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is
available for development support. This hardware has the
capability to program single devices.
The emulator consists of a base unit that connects to the PC by
way of a USB port. The base unit is universal and operates with
all enCoRe and PSoC devices. Emulation pods for each device
family are available separately. The emulation pod takes the
place of the PSoC device in the target board and performs full
speed (24 MHz) operation.

Designing with PSoC Designer
The development process for the enCoRe V device differs from
that of a traditional fixed function microprocessor. Powerful
PSoC Designer tools get the core of your design up and running
in minutes instead of hours.
The development process can be summarized in the following
four steps:
1. Select Components
2. Configure Components
3. Organize and Connect
4. Generate, Verify, and Debug
Select Components
The chip-level view provides a library of pre-built, pre-tested
hardware peripheral components. These components are called
“user modules.” User modules make selecting and implementing
peripheral devices simple, and come in analog, digital, and
mixed-signal varieties.
Configure Components
Each of the components you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application.
The chip-level user modules are documented in data sheets that
are viewed directly in PSoC Designer. These data sheets explain
the internal operation of the component and provide performance specifications. Each data sheet describes the use of each
user module parameter and contains other information you may
need to successfully implement your design.
Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on to developing code for the project, you perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system.
Both system-level and chip-level designs generate software
based on your design. The chip-level design provides application
programming interfaces (APIs) with high level functions to
control and respond to hardware events at run time and interrupt
service routines that you can adapt as needed. The system-level
design also generates a C main() program that completely
controls the chosen application and contains placeholders for
custom code at strategic positions allowing you to further refine
the software without disrupting the generated code.
A complete code development environment allows you to
develop and customize your applications in C, assembly
language, or both.
The last step in the development process takes place inside
PSoC Designer’s Debugger (access by clicking the Connect
icon). PSoC Designer downloads the HEX image to the In-Circuit
Emulator (ICE) where it runs at full speed. PSoC Designer
debugging capabilities rival those of systems costing many times
more. In addition to traditional single-step, run-to-breakpoint and
watch-variable features, the debug interface provides a large
trace buffer and allows you to define complex breakpoint events
that include monitoring address and data bus values, memory
locations and external signals.
Organize and Connect
You build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins, or connect system-level
inputs, outputs, and communication interfaces to each other with
valuator functions. In the chip-level view, you perform the
selection, configuration, and routing so that you have complete
control over the use of all on-chip resources.

Register Reference
The section discusses the registers of the enCoRe V device. It lists all the registers in mapping tables, in address order.
Register Conventions
Register Mapping Tables
The register conventions specific to this section are listed in the
following table.
The enCoRe V device has a total register address space of 512
bytes. The register space is also referred to as IO space and is
broken into two parts: Bank 0 (user space) and Bank 1 (configuration space). The XIO bit in the Flag register (CPU_F) determines which bank the user is currently in. When the XIO bit is
set, the user is said to be in the “extended” address space or the
“configuration” registers.

3. Higher storage temperatures reduce data retention time. Recommended storage temperature is +25°C ± 25°C. Extended duration storage temperatures above 85oC
degrade reliability.
4. Human Body Model ESD.
5. According to JESD78 standard.
6. The temperature rise from ambient to junction is package specific. See Package Handling on page 25. The user must limit the power consumption to comply with this
requirement.

Notes
15. A Fast mode I2C bus device can be used in a standard mode I2C bus system, but the requirement tSU;DAT ≥ 250 ns must then be met. This is automatically the case if the device does not stretch the
LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the
standard mode I2C bus specification) before the SCL line is released.

Package Handling
Some IC packages require baking before they are soldered onto a PCB to remove moisture that may have been absorbed after leaving
the factory. A label on the package has details about the actual bake temperature and the minimum bake time to remove this moisture.
The maximum bake time is the aggregate time that the parts exposed to the bake temperature. Exceeding this exposure may degrade
device reliability.
