За 100 раз только один раз определилась как Cypress EZ-USB FX2LP - EEPROM missing
Cхема включения в файле
Судя по наличию вывода
EA, используется корпус TQFP128.

5.3.2 128 Pin EZ-USB Chip:
"
EA = 1 All program memory is off-chip; all on-chip RAM, including the main RAM, is data memory only.
The EZ-USB reads all on-chip RAM using only the RD# strobe; the combining of RD# and PSEN# is disabled,
so the on-chip RAM becomes data memory only. All program memory is off-chip; accesses to the lower 16 KB of off-chip program memory are not inhibited.
Any code fetch asserts the PSEN# pin.
After a power on reset, the EZ-USB immediately begins executing code at address 0x0000 in the off-chip program memory (as long as there is no EEPROM on the I2C bus with a valid 0xC0 or 0xC2 signature byte), rather than waiting for an EEPROM load or USB code download to complete (see the Resets chapter on page 95 for a full description of the EZ-USB resets).
