we try to use CY14B101P memory with SPI and RTC in AUTOSTORE MODE. on product datasheet at page 3 in table 1 Pin definition the CS pin active the device when is pulled low (GND?? or not connected??). BUT at page 5(of34) on FIgure n.2 Autostore mode the CS is pulled on Vcc with a 10k resistor ( always pulled up when the power in on!!! )
in onother datasheet of product similar ( nvram with RTC but not WITHOUT SPI interface) CY14B101KA at page 4 there is the same drow (figure2 autostore mode) but this thime WE is pulled on wcc with 10 k resistor and this provably is the true configuration!!
on another cypress document the application note AN43593 on page 1 the drow FIgure 1 report a autostore configuration equals then CY14B101KA datasheet..!
another question: we use single chip mode : the HOLD pin is pulled on vcc or gnd for work???
please inform me about the error ! we loss a lot of time for redrow our project!!!
