Electrical Specifications
This chapter presents the DC and AC electrical specifications of the CY8C27x43 PSoC device. For the most up to date electrical
specifications, confirm that you have the most recent data sheet by going to the web at http://www.cypress.com/psoc.
Specifications are valid for -40°C ≤ T
A
≤ 85°C and T
J
≤ 100°C, except where noted. Specifications for devices running at greater than
12 MHz are valid for -40°C ≤ T
A
≤ 70°C and T
J
≤ 82°C.
