the high-performance, low-power v853 microcontroller features the advanced 32-bit risc engine of necs v850 ? family. with 128k of on-chip, single-cycle flash memory, designers have the flexibility to perform in-system programming of devices, decreasing product development upgrade cycles. the v853 microcontroller provides a wide array of on-chip peripherals for embedded applications, including two uarts, four clocked serial interfaces, three baud rate generators, one 12-bit pulse-width modulator, one 10-bit a/d converter, and one 8-bit d/a converter. many versions of the v850 core are available as part of necs asic library. the architecture of the v853 device is highly optimized for fast dsp-like operation and very efficient implementation of c programmability. v853 ? 32-bit risc microcontroller specifications block diagram clock frequency: dc to 33 mhz performance C 38 dhrystone mips C 88 mips/w two-cycle mac instruction single-cycle frequency shift 5v operation power consumption: 431 mw at 33 mhz 0.5 m cmos process technology 6.4 mm x 6.5 mm die size package C 100-pin plastic qfp C 14 mm x 14 mm 96fm-1037c (11/98) alu nmi astb cksel clkout rom/flash sio cpu bcu ram to110?11 to120?21 to130?31 to140?41 intp110?13 intp120?23 intp130?33 intp140?43 pwm0? mode ano0, ano1 av ref2, av ref3 ad 0 ?d 15 a 16 ? 19 dstb r/w uben lben wait hldrq hldak reset x1 x2 clock generator system control programmable interrupt controller real-time pulse unit 128k 4k 32-bit barrel shifter pc system register general- purpose registers (32-bit x 32) multiplier 16 x 16 32 bus control unit instruction queue port d/a converter adtrg av dd av ss av ref1 ani0?ni7 d/a converter tclr1 ti1 brg0 so2 si2 sck2 so0/txd0 si0/rxd0 sck0 uart0/ csi0 brg1 p0 ... p11 so1/txd1 si1/rxd1 sck1 uart1/ csi1 brg2 csi3 so3 si3 sck3 pwm csi2 ?? s e r i e s 850 850 s e r i e s
