128M NOR+64M Psram

The CAT24C32 is a 32-kb I2C serial EEPROM device internally organized as 4096 words of 8 bits each. It has a 32-byte page write cache and supports standard (100 kHz), fast (400 kHz), and ultra-fast (1 MHz) I2C protocols. External address pins make it possible to place up to eight CAT24C512 devices on the same bus.

4-Mbit(512K x8bit), SPI, Dual SPI, Quad SPI, 120MHz, voltage: 2.7V to 3.6V

1-Mbit (128K x 8bit), I2C interface, working voltage: 1.8V to 5.5V
