MR45V032AMAZBATL from ROHM Semicon, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	CS#	input	Chip Select (negative logic): a low input latches the address, activates the FeRAM, and enables a read or write operation; CS# should be low during hold operation.
2	SO	tri_state	Serial output; the pin is High-Z when CS# is not active or when HOLD# is low.
3	WP#	input	Write Protect (negative logic) controls write operations to the status register (BP0, BP1) and should be fixed low or high during write operations.
4	VSS	power_in	Ground; connect to system ground (0 V).
5	SI	input	Serial input for operation code, addresses, and data; SI is don't care while HOLD# is low.
6	SCK	input	Serial clock input; inputs are latched on the rising edge and outputs occur on the falling edge, with operating frequency up to 15 MHz.
7	HOLD#	input	Hold (negative logic) suspends serial communication without disabling the chip; when low, SO is High-Z and SI/SCK are don't care, and CS# must remain low.
8	VCC	power_in	Power supply; the specified recommended operating range is 2.7 V to 3.6 V (3.3 V typ).
