ikipedia PSoC (Programmable System-on-Chip) is a family of microcontroller integrated circuits byCypress Semiconductor . These chips include a CPU core and mixed-signal arrays of configurable integrated analog and digital peripherals.
History [edit !n "##"$ Cypress began shipping commercial %uantities of the PSoC &. [& To promote the PSoC$ Cypress sponsored a 'PSoC esign Challenge' in Circuit Cellar magaine in "##" and "##*.[" !n +pril "#&,$ Cypress released the fourth generation$ PSoC *. The PSoC * features a ,"-bit + Cortex-# CPU$ /ith programmable analog bloc0s ( operational amplifiers and comparators)$ programmable digital bloc0s (P1-based U2s)$ programmable routing and flexible 3P!4 (route any function to any pin)$ a serial communication bloc0 (for SP!$ U+T$ !5C)$ a timer6counter6P7 bloc0 and more.[, PSoC is used in de8ices as simple as Sonicare toothbrushes and +didas snea0ers$ and as complex as the Ti9o set-top box. 4ne PSoC$ using CapSense$ controls the touch-sensiti8e scroll /heel on the +pple iPod clic0 /heel. !n "#&*$ Cypress extended the PSoC * family by integrating a 2luetooth 1o/ :nergy radio along /ith a PSoC * Cortex-#-based SoC in a single$ monolithic die.
Overview [edit + PSoC integrated circuit is composed of a core$ configurable analog and digital bloc0s$ and programmable routing and interconnect. The configurable bloc0s in a PSoC are the biggest difference from other microcontrollers. PSoC has three separate memory spaces; paged S+ for data$ only startup code that is created by Cypress? PSoC Designer (for PSoC &) or PSoC Creator (for PSoC , 6 * 6 @) !:. PSoC resembles an
Creator generate the startup configuration code. 2oth integrate +P!s that initialie the user selected components upon the users needs in a9isual-Studio-li0e 3U!.
Configurable analog and digital blocks [edit
PsoC 2loc0 :xample
Using configurable analog and digital bloc0s$ designers can create and change mixed-signal embedded applications. The digital bloc0s are state machines that are configured using the bloc0s registers. There are t/o types of digital bloc0s$ igital 2uilding 2loc0s (22xx) and igital Communication 2loc0s (C2xx). 4nly the communication bloc0s can contain serial !64 user modules$ such as SP!$ U+T$ etc. :ach digital bloc0 is considered an A-bit resources that designers can configure using pre-built di gital functions or user modules (U)$ or$ by combining bloc0s$ turn them into &B-$ "*-$ or ,"-bit resources. Concatenating Us together is ho/ &B-bit P7s and timers are created. There are t/o types of analog bloc0s. The continuous time (CT) bloc0s are composed of an op-amp circuit and designated as +C2xx /here xx is ##-#,. The other type is the s/itch cap (SC) bloc0s$ /hich allo/ complex analog signal flo/s and are designated by +SCxy /here x is the ro/ and y is the column of the analog bloc0. esigners can modify and personalie each module to any design.
Programmable routing and interconnect [edit PSoC mixed-signal arrays? flexible routing allo/s designers to route signals to and from !64 pins more freely than /ith many competing microcontrollers. 3lobal buses a llo/ for signal multiplexing and for performing logic operations. Cypress suggests that this all o/s designers to configure a design and ma0e impro8ements more easily and faster and /ith fe/er PC2 redesigns than a digital logic gate approach or competing microcontrollers /ith more fixed function pins.
Series[edit PSoC is a soft/are configured$ mixed-signal array /ith a built-in microcontroller core. There are four different families of de8ices$ each based around a different microcontroller core; •
PSoC & - CAC"xxxx series > AC core.
•
PSoC , - CAC,xxxx series - A#@& core.
•
PSoC * - CAC*xxxx series - + Cortex-# core.[*
•
PSoC @ - CAC@xxxx series - + Cortex-, core.
Bluetooth Low Energy Starting in "#&*$ Cypress began offering PSoC * 21: de8ices /ith integrated 2luetooth 1o/ :nergy (2luetooth Smart). This can be used to create connected products le8eraging the analog and digital bloc0s.[@ Users can add and configure the 21: module directly in PSoC creator. Cypress also pro8ides a complete 2luetooth 1o/ :nergy stac0 licensed from indtree /ith both Peripheral and Central functionality.[B

Development tools[edit PSoC esigner [edit This is the first generation soft/are !: to design and debug and program the PSoC & de8ices. !t introduced uni%ue features including a library of pre-characteried analog and digital peripherals in a drag-and-drop design en8ironment /hich could then be customied to specific design needs by le8eraging the dynamically generated +P! libraries of code.
PSoC Creator [edit PSoC Creator is the second generation soft/are !: to design debug and program the PSoC , 6 * 6 @ de8ices. The de8elopment !: is combined /ith an easy to use graphical design editor to form a po/erful hard/are6soft/are co-design en8ironment. PSoC Creator consists of t/o basic building bloc0s. The program that allo/s the user to select$ configure and connect existing circuits on the chip and the components /hich are the e%ui8alent of peripherals on CUs. 7hat ma0es PSoC intriguing is the possibility to create o /n application specific peripherals in hard/are. Cypress publishes component pac0s se8eral times a year. PSoC users get ne/ peripherals for their existing
hard/are /ithout being charged or ha8ing to buy ne/ hard/are. PSoC Creator also all o/s much freedom in assignment of peripherals to !64 pins.
