Package

The S29AL032D90TFI040 is packaged in a TSOP (Thin Small Outline Package), specifically a 48-pin TSOP type I package. This package type is designed for surface mounting and is commonly used for flash memory devices.

Pinout

The S29AL032D90TFI040 is a 32Mb (4MB) Flash memory device from Spansion (now part of Cypress Semiconductor). It features a total of 44 pins. This device uses the TSOP (Thin Small Outline Package) form factor.
The primary functions of the pins include:
- Address Pins (A0 - A21): Used to select the memory locations.
- Data Pins (DQ0 - DQ15): These are the data input/output pins for read and write operations.
- Control Pins:
- WE# (Write Enable): Activates the write operation.
- RE# (Read Enable): Activates the read operation.
- CE# (Chip Enable): Selects the chip for reading/writing.
- OE# (Output Enable): Enables output data.
- VCC and GND: Power supply and ground connections.
- WP# (Write Protect): Protects the memory against write operations when asserted.
This organization allows for efficient access and control of the Flash memory.
