Memory: SST39SF010A-70-4I-NHE-T

SST39SF010A-70-4I-NHE-T is a widely used Dynamic Random Access Memory (DRAM) device developed by the manufacturer Silicon Storage Technology, Inc. (SST). The device is a CMOS 4096K x 8 bit Parallel EEPROM with a maximum clock frequency of 70 MHz. It is also designed for backwards compatibility and is pin-to-pin compatible with the SST39F010, SST39F020, SST39F040, SST39VF010, SST39VF020, SST39VF040, and SST39VF080 devices.

The SST39SF010A-70-4I-NHE-T integrates a control logic block, a 6-bit counter, instruction register, address register and five SRAM cell banks. The 6-bit counter is used to keep track of the address and data which are being transferred. It also provides an internally generated address sequence, which is used to allow for fast write/read operations. The address register is used to store a 6-bit counter value which is used to point to the beginning location of the address sequence.

The SST39SF010A-70-4I-NHE-T also has an internal clock oscillator, which can generate its own clocks from an external power source. The device also has a power-down mode, which can be used when the device is not being accessed or attended. This allows the device to conserve power, which is especially important for battery operated products.

The SST39SF010A-70-4I-NHE-T device is designed for applications such as: cellular phones, PDAs, battery-powered devices, GPS devices, wearables and medical equipment. It is an ideal solution for storing critical code and application data in a compact, low-power module. It is also capable of supporting multiple I/O standards, such as: I2C, SPI, and parallel memory. It is also designed to be extremely reliable and to protect against data lose.

In terms of working principle, the SST39SF010A-70-4I-NHE-T uses the memory mapping architecture that consists of two phases: read and write. During each phase, data is read/written to or from a predefined location on the chip. In many chips, a pointer location register is used to keep track of the address which is being accessed. When a certain address is selected, an instruction is received by the on-chip logic and memory cells. Depending on the type of instruction, data is written to or read from the chosen address.

In conclusion, the SST39SF010A-70-4I-NHE-T offers an excellent solution for a wide range of embedded applications due to its low-power consumption, reliable operation, and the support for multiple I/O standards. It enables optimal usage of critical code and application data in a compact form factor. The SST39SF010A-70-4I-NHE-T uses the memory mapping architecture to read and write data from predefined locations on the chip. The device is also designed to be extremely reliable and to protect against data loss.
