Cypress.com: Documentation http://www.cypress.com/?app=search&searchType=advanced&id%3D3135 User Module Datasheet: 8-Bit Counter Datasheet Counter8 V 2.60 (CY8C29/27/24/22/21xxx, CY8C23x33, CYWUSB6953, CY7C64215, CY8CLED02/04/08/16, CY8CLED0xD, CY8CLED0xG, CY8CTST110, CY8CTMG110, CY8CTST120, CY8CTMG120, CY8CTMA120, CY8CTMA140, CY8C21x45, CY8C22x45, CY8CTMA30xx, CY8C28x45, CY8CPLC20, CY8CLED16P01, CY8C21x12) http://www.cypress.com/?rID=3128 Features and Overview

  • The 8-bit general purpose counter uses one PSoC block
  • Source clock rates up to 48 MHz
  • Automatic reload of period on terminal count
  • Programmable pulse width
  • Input enables/disables continuous counter operation
  • Interrupt option on compare output or terminal count
     

The 8-Bit Counter User Module provides a down counter with a programmable period and pulse width. The clock and enable signals can be selected from any system time base or external source. Once started, the counter operates continuously and reloads its internal value from the period register upon reaching terminal count. During each clock cycle, the counter compares the current count to the value stored in the compare register. Each clock cycle, the Counter tests the count against the value of the compare register for either a “less than" or “less than or equal to" condition. The comparator output provides a logic level that may be routed to pins and to other user modules. Most PSoC device families also permit the terminal count output to be routed in the same manner.

CY8C22x45, CY8C21345: PSoC® Programmable System-on-Chip™ Technical Reference Manual (TRM) http://www.cypress.com/?rID=37728
The PSoC® family consists of many mixed-signal arrays with on-chip controller devices. As described in this technical reference manual (TRM), a PSoC device includes configurable blocks of analog circuits and digital logic, as well as programmable interconnect. This architecture allows the user to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable input/output (IO) are included in a range of pinouts.

This document is a technical reference manual for all PSoCs with a base part number of CY8C2xxxx, except for the CY8C25122 and CY8C26xxx PSoC devices. It also applies to CY7C64215, CY7C603xx, and CYWUSB6953.
