The fastest rectifiers in the west
The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
Ferroelectric RAM handles repeated rewrites
The FM24C04 4Kbit FRAM serial memory from Solid State Supplies is ideal for nonvolatile memory applications which require frequent or rapid writing.
In keeping with Solid Stateûs commitment to enduring excellence, other functions are compatible with it's predecessor, the HT49R50A-1.
In the low-power mode function, a real-time clock oscillator is provided, enabling the implementation of a timer function when the MCU is in its power down mode.
The device also permits the function of the LCD to remain fully operational when the processor is in its power down mode.
By incorporating a range of ROM LCD options within the microcontroller, the interface to the LCD is simplified, allowing the user can select the required bias and comms options to match the LCD being used.
In addition, by using a RAM mapping method, the system to LCD panel interface and operation is made much simpler.
With these special features, the HT49R30A-1 device is especially equipped for a wide range of LCD display applications such as scales, water meters, electricity meters, gas meters, timers, calculators, remote control devices as well as a range of household appliances.
