Tekmos, Inc. recently introduced the first true pin for pin, code and timing compatible drop in replacement for the Freescale MC68HC05B6 microcontroller. The TK68HC05B6 provides 256 bytes of EEPROM, 16 bit timer, two PWM, watch dog timer, 8 channel A/D converter, 24 bit bi-directional I/O lines, on chip oscillator with crystal/ceramic resonator and serial communications capability. The TK68HC05B6 is currently packaged in a 52 PLCC. Other package offerings supported include 64 QFP and custom adapter solutions for the 56 SDIP. The TK68HC05B6 will be sampled this month. The 52 PLCC version is priced at $1.30 in 10,000 pc quantities. There is a mask programming charge of $5000 for each device code. An FPGA based customer evaluation board is available now for customers wishing to verify the Tekmos TK68HC05B6 design in their products.
