The CY27EE16ZEC is field programmable while the CY27EE16ZEC-300 is factory programmable. Other than this there is no difference between the two. These parts have long been obsoleted by Cypress.
Yes we know this part is been obsolete for long time but it had a very
short life time.
It is possible to get the CY27EE16ZEC-300 field programmable ?
