Product Overview
DS4520E+TRL is a 9-bit non-volatile (NV) I/O expander with 64 bytes of NV user memory controlled by an I²C compatible serial interface. It offers users a digitally programmable alternative to hardware jumpers and mechanical switches that are being used to control digital logic nodes. Furthermore, the digital state of each pin can be read through the serial interface. Each I/O pin is independently configurable. The outputs are open drain with selectable pullups. Each output has the ability to sink upto 12mA. Since the device is NV, it powers up in the desired state allowing it to control digital logic inputs immediately on power-up without having to wait for the host CPU to initiate control. It is used in applications such as RAM-based FPGA bank switching for multiple profiles, selecting between boot flash, setting ASIC configurations/profiles, servers, network storage, routers, telecom equipment, PC peripherals.
- Programmable replacement for mechanical jumpers and switches
- Nine NV input/output pins, 64-byte NV user memory (EEPROM)
- I²C-compatible serial interface, upto 8 devices can be multi dropped on the same I²C bus
- Open-drain outputs with configurable pullups, outputs capable of sinking 12mA
- Low power consumption, wide operating voltage range from 2.7V to 5.5V
- Standby current is 2µA typical at (VCC = +2.7V to +5.5V; TA = -40°C to +85°C)
- I/O capacitance is 10pF maximum at (VCC = +2.7V to +5.5V; TA = -40°C to +85°C)
- SCL clock frequency is 400KHz maximum at (VCC = +2.7V to +5.5V; TA = -40°C to +85°C)
- Power-on reset voltage is 1.6V typical at (VCC = +2.7V to +5.5V; TA = -40°C to +85°C)
- Operating temperature range from -40°C to +85°C, 16-lead TSSOP package
