Checksum Error With CY2292F
When using a Chipmaster6000 Universal Programmer Ver 4.40 with Socket Adapter SDP-UNIV-16SO, trying to program CY2292F with jedec file, Checksum = 10BA(H) the result is checksum = 141C(H). What is wrong?

Voh of 2.4V Minimum with a 3.3V Supply (CY2292F)
Why does Cypress specify a Voh of 2.4 v min with a 3.3v supply when in fact the measurement shows a voltage exceeding 0.95 vcc (close to 3.3 v)? This device is to be used to drive a clock pin that requires the CMOS range not, the TTL 2.4 v range of level for the logic high.)

Eight Different Values Programming Possibility in CY22394
It is possible in the CY22394 to select eight different values of the frequency of PLL 1 using the start-up values of S0, S1 and S2. However, is it possible to program them to flash using software?

CY22393 Frequency Array Table: 8x3 registers Register Requirement
Why does the SONOS Frequency Array Table of part CY22393 include 8x3 registers for the configuration of the PLL1 (40h to 57h) when S2 has only 2 bits? The 4x3 registers seem to be sufficient (40h to 4Bh).

Programming the CY22150 with FPGA
When using an FPGA on a PCB for serial programming of the CY22150, during write mode, the device will respond with an ACK pulse after eight bits by pulling the SDAT line low. Is this a 'weak 0', or a 'strong 0'? Can there be a conflict with the I/O of the FPGA?
