Can any one tell me guide me for requirment of CRYSTAL oscillator for CY8C20434.
The 434 has an input for external clock should you need greater
accuracy than the onboard +/- 5% clock. External clock would be
governed by your requirements for -
1) Timing accuracy you require
2) Operating voltage
4) Temp requirements
Thanks for info. Conclude at not to use a crystal.
The CY8C20434 does not need a crystal, it has got two independent internal oscillators, see datasheet http://www.cypress.com/?docID=38076
