Overview The Cypress Envirosystems Wireless Pneumatic Thermostat (WPT) retrofits an existing pneumatic thermostat to provide Direct Digital Control (DDC) like zone control functionality at a fraction of the time and cost without disturbing occupants. The WPT enables remote monitoring of zone temperature, branch pressure, remote control of setpoints, and programmable setback or setup of the pneumatic HVAC systems. It also enables integration with utility Demand Response programs. The WPT USB Hub

Guaranteed by statistical correlation. Tested initially and after any design or process changes that may affect these parameters. 9. CMOS output buffer current and power dissipation specified at 50 MHz reference frequency. 10. Applies to REF and FB inputs only. 11. Test measurement levels for the CY7B9910 are TTL levels (1.5V to 1.5V). Test measurement levels for the CY7B9920 are CMOS levels (VCC/2 to VCC/2). Test conditions assume signal transition times of 2ns or less and output loading as sho

The CY7C1353G is equipped with the advanced No Bus Latency™ (NoBL™) logic required to enable consecutive Read/Write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data through the SRAM, especially in systems that require frequent Write-Read transitions. All synchronous inputs pass through input registers controlled by the rising edge of the clock. The clock input is qualified by the Clock Enable (CEN) signal, which when deasserte
