71321SA55JG - Renesas Electronics

Description: The 71321 is a high-speed 2K x 8 Dual-Port Static RAM with internal interrupt logic for interprocessor communications. It is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the 71421 "SLAVE" Dual-Port in 16-bit-or-more word width systems which would result in full-speed, error free operation without the need for additional discrete logic. An automatic power down feature, controlled by CE, permits the on chip circuitry of each port to enter a very low sta

71321SA55JG Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 71321SA55JG is -40°C to 125°C.
  • The POR sequence for the 71321SA55JG involves applying power to the VCC pin, followed by a delay of at least 10ms to allow the internal voltage regulator to stabilize, and then releasing the reset pin (RST) to allow the device to start executing code.
  • The maximum clock frequency supported by the 71321SA55JG is 32MHz.
  • To configure the 71321SA55JG for low-power operation, set the clock frequency to the lowest possible value, enable the internal voltage regulator, and use the power-down mode (PDN) to reduce power consumption when the device is not in use.
  • The built-in voltage regulator on the 71321SA55JG is used to generate the internal voltage supply (VCC) from an external power source, allowing the device to operate from a single power supply voltage.
