PSoC® Analog Coprocessor:
CY8C4Axx Family Datasheet
Programmable System-on-Chip (PSoC®)
General Description
Cypress' PSoC® Analog Coprocessor is a scalable and reconfigurable platform architecture of programmable analog coprocessors
that simplify designing embedded systems with multiple sensors. The PSoC Analog Coprocessor device combines PSoC's flexible
Analog Front Ends, programmable analog filters, and high-resolution analog-to-digital converters along with an efficient yet powerful
32-bit Arm® Cortex®-M0+ based signal processing engine – enabling host processors to easily fetch aggregated, pre-processed, and
formatted complex sensor data over serial communication interfaces.
Features
Programmable Analog Blocks
A switched-capacitor Universal Analog Block (UAB) program-
mable via PSoC Creator as a second-order analog filter, a
12-bit Incremental Delta-Sigma ADC, or two 13-bit Voltage
DACs
Two dedicated analog-to-digital converters (ADC) including a
12-bit SAR ADC and a 10-bit single-slope ADC
Four opamps, two low-power comparators, and a flexible
38-channel analog mux to create custom Analog Front Ends
(AFE)
Two 7-bit Current DACs (IDACs) for general-purpose or capac-
itive sensing applications on any pin
CapSense® Capacitive Sensing
Cypress's fourth-generation CapSense Sigma-Delta (CSD)
providing best-in-class signal-to-noise ratio (SNR) and water
tolerance
Cypress-supplied software component makes capacitive
sensing design easy
Automatic hardware tuning (SmartSense™)
Segment LCD Drive
LCD drive supported on all pins (common or segment)
Operates in Deep-Sleep mode with four bits per pin memory
Programmable Digital Peripherals
Three independent serial communication blocks (SCBs) that
are run-time configurable as I2C, SPI or UART
Eight 16-bit timer/counter/pulse-width modulator (TCPWM)
blocks with center-aligned, edge, and pseudo-random modes
32-bit Signal Processing Engine
Arm Cortex-M0+ CPU up to 48 MHz
Up to 32 KB of flash with read accelerator
Up to 4 KB of SRAM
Eight-channel descriptor-based DMA controller
Low-Power Operation
1.71-V to 5.5-V operation
Deep-Sleep mode with operational analog and 2.5-µA digital
system current
Watch Crystal Oscillator (WCO)
Programmable GPIO Pins
Up to 38 GPIOs that can be used for analog, digital, CapSense,
or LCD functions with programmable drive modes, strength and
slew rates
Includes eight Smart I/Os to implement pin-level Boolean
operations on input and output signals
48-pin QFN, 48-pin TQFP, 28-pin SSOP, and 45-ball WLCSP
packages
PSoC Creator Design Environment
Integrated Design Environment (IDE) provides
schematic-capture design entry and build (with automatic
routing of analog and digital signals) and concurrent firmware
development with an Arm-SWD debugger
GUI-based configurable PSoC Components with fully
engineered embedded initialization, calibration and correction
algorithms
Application Programming Interfaces (API) for all fixed-function
and programmable peripherals
Industry-Standard Tool Compatibility
After schematic-capture, firmware development can be done
with Arm-based industry-standard development tools

Software User Guide:
A step-by-step guide for using PSoC Creator. The software
user guide shows you how the PSoC Creator build process
works in detail, how to use source control with PSoC Creator,
and much more.
Component Datasheets:
The flexibility of PSoC allows the creation of new peripherals
(components) long after the device has gone into production.
Component datasheets provide all the information needed to
select and use a particular component, including a functional
description, API documentation, example code, and AC/DC
specifications.
Online:
In addition to print documentation, the Cypress PSoC forums
connect you with fellow PSoC users and experts in PSoC
from around the world, 24 hours a day, 7 days a week.
Technical Reference Manual (TRM) is in two documents:
Architecture TRM details each PSoC 4 functional block.
Registers TRM describes each of the PSoC 4 registers.
Development Kits:
CY8CKIT-048: A full-featured development board for PSoC
Analog Coprocessor with five onboard sensors, onboard
debugger, and an Arduino shield compatible form-factor.
The MiniProg3 device provides an interface for flash
programming and debug.
