Atmel AT73C500
The AT73C500 is based on an efficient digital signal processor (DSP) core and it supports interfacing both with the AT73C501 and with an external microprocessor. The AT73C500 DSP can also be used with the differential input ADC, AT73C502. With this chipset, only a minimum of discrete components is required to develop products ranging from simple domestic Watt-hour meters to sophisticated industrial meters.| Part No. | AT73C500 |
