CY7C1339G-133AXC is a 16Mbit pseudo static RAM (PSRAM) that includes static RAM (SRAM) blocks, an asynchronous address and data multiplex bus interface, memory blocks, and control logic. Ideal for low-power embedded applications, it is available in an industrial temperature grade and supports burst and single-access operations. This device consists of address latch, address control logic, refresh logic and data register. Asynchronous bus control logic is also included, so address and data can be transferred without the need for a system clock. It also offers double data rate (DDR) user mode and features configurable write protection. CY7C1339G-133AXC is suitable for applications in computer systems, small appliances, embedded controllers, data storage, and analog systems.

One of the primary functions of the CY7C1339G-133AXC is to store data. It features two 16Mbit SRAM blocks. These SRAM blocks can be read or written to any address in the memory by issuing commands via the asynchronous address and data multiplex bus. The memory interface control logic can transfer addresses and data from the bus interface to the internal SRAM, allowing the user to control the data to be stored. In addition, the memory interface control logic can also issue various control signals and commands, like chip enable, write enable, and read enable to the SRAM.

The CY7C1339G-133AXC also includes an address latch, address control logic, and refresh logic. The address latch allows the address signals to be held while the address control logic determines the performance of the read and write cycles. The address control logic also controls the timing of the address signals. The refresh logic helps in monitoring the activity of the SRAM memory to ensure data integrity.

CY7C1339G-133AXC also supports various single-access and burst operations. In single-access mode, only one data address can be accessed and data can be read or written from the SRAM. In burst mode, multiple addresses can be accessed and data can be transferred from the SRAM. This allows the user to access data faster. In addition, the device also supports write protection, which prevents accidental overwriting of data.

The asynchronous bus control logic of the CY7C1339G-133AXC is used to transfer address and data signals from the bus interface to the internal SRAM. This logic is designed to be compatible with different bus protocols. It also contains a configurable Write-Protect bit and a DDR user mode, which allows the user to optimize the device for different operating conditions.

In conclusion, the CY7C1339G-133AXC is a 16Mbit PSRAM which is ideal for low-power embedded applications. It includes two 16Mbit SRAM blocks, an asynchronous bus control logic, address latch, address control logic, and refresh logic. It supports various single-access and burst operations and also provides write protection to prevent accidental overwriting of data. The device is suitable for applications in computer systems, small appliances, embedded controllers, data storage, and analog systems.
