PRELIMINARY CY8CNP102B, CY8CNP102E

The last step in the development process takes place inside the PSoC Designer’s Debugger subsystem. The Debugger downloads the HEX image to the In-Circuit Emulator (ICE) where it runs at full speed. The Debugger capabilities rival those of systems costing much more. In addition to traditional single step, run to breakpoint, and watch variable features, the Debugger provides a large trace buffer enabling you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals.

Cypress nvSRAM user Module

The nvSRAM user module is integrated with the PSoC Designer tool and contains APIs that facilitate nvSRAM access and control. The user module provides high level access to the nvSRAM without user developed code. The user module API also provides the ability to read and write arbitrary data struc- tures to or from the nvSRAM, and initiate nvSRAM Store or Recall operations.

Electrical Specifications

This section lists the PSoC NV device DC and AC electrical specifications. Specifications are valid for -40oC TA 85oC, and TJ 100oC, except where noted.

Refer Table 14 on page 17 for electrical specifications on the Internal Main Oscillator (IMO) using SLIMO mode.
