CMOS transceiver circuit builds a compact RFID reader News & Analysis 11/25/2003 Post a comment EM Microelectronic offers a practical circuit for an RFID card reader. The author offers instructions for configuring the circuit for read-only, read-write and passive transponder applications. Because the operation is dependent on the resonance of the RFID card with its reader, tuning capacitor selection can be critical, he advises.
Reusable architecture is DSP framework Product News 11/24/2003 Post a comment Over a decade ago, fixed-point digital signal processor implementations became available, enabling easy software programmability for different DSP algorithms. Those early DSPs offered limited processing capabilities that could have been used for specific uncomplicated tasks such as voice compression and decompression. Over the years, DSP usage has spread to other applications including audio decoding and encoding, signal modulators and equalizers, different video applications, and advanced vocod
First AE-5 Series 32-Bit Smart Card MCU from Renesas Product News 11/24/2003 Post a comment The AE57C is the first product from Renesas Technology Corp.'s AE-5 Series of 32-bit smart card microcontrollers. According to the company it offers approximately four times the , but offers approximately four times the processing performance of the AE-4 Series as it executes one instruction per cycle instead of one instruction in two cycles. The chip comes with 132 KB of EEPROM, the largest memory capacity of any of the company's smart card microcontrollers.
