✦ Synopsis
Integrated SLEEP mode power management High Precision pulse width modulation -24.4KHz @ 10 bit resolution I2CTWSPI TM port with master mode support and dual channel USART Microchip's PIC 17C756 is the first device in their new PICI7C75X family of high-performance 8-bit one-time-programmable (OTP) micro-controllers with a 10-bit A/D converter in 64-and 68-pin packages. The PIC17C756 has a performance of 8.25 MIPS CPU at 33 Mhz and single cycle (120 nanoseconds) 8 x 8 hardware multiply providing engineers with a high performance system. The PIC17C756 includes two 8.25 million bits per second USARTs, up to 16K x 16 of OTP on-chip program memory and up to 902 x 8 bytes of user RAM. The high-precision 10-bit 12-channel A/D converter offers a high-speed conversion rate and can convert while in sleep mode. Other peripheral features include up to 50 1/O pins with individual direction control, 4 pins configurable as capture input (120 ns resolution), 3 pins configurable as PWM output (1-10 bits resolution with 130 kHz at 8 bits and 32 kHz at 10 bits), local communications capability for peripheral expansion (I2C/SPI compatible) and 4 timers (two 8-bit and two 16-bit). In addition, the large program and data memory and affordable OTP make the PIC17C756 ideal for demanding realtime embedded control applications such as settop boxes, motion and process control, instrumentation, UPS, printer, plotter copier, ABS, air bag controllers, security, network switches, modems and data encryption. The PIC17C756 is supported by the PICMASTER®-17B Universal Development System, a fully-integrated programming development and emulation system. A low-cost development system, PICSTART® Plus, is also available as well as the MPLAB TM development software suite and a programmer supported by an assembler and software simulator tools. Other tools include the MP-DriveWay TM Automatic Application Code Generator, the MPLAB-C compiler and fi~z~.¢ logic tools. The package is shown below and a diagram of the system is shown in opposite.
