PIC14000
1.0 GENERAL DESCRIPTION
The PIC14000 features include medium to high resolution A/D conversion (10 to 16 bits), temperature sensing, closed loop charge control, serial communication, and low power operation. The PIC14000 uses a RISC Harvard architecture CPU with separate 14-bit instruction and 8-bit data buses. A two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches, which require two cycles. A total of 35 instructions are available. Additionally, a large register set is included. PIC16/17 microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers. The internal band-gap reference is used for calibrating the measurements of the analog peripherals. The calibration factors are stored in EPROM and can be used to achieve high measurement accuracy. Power savings modes are available for portable applications. The SLEEP and HIBERNATE modes offer different levels of power savings. The PIC14000 can wake up from these modes through interrupts or reset. A UV erasable CERDIP packaged version is ideal for code development, while the cost-effective One-Time Programmable (OTP) version is suitable for production in any volume. The PIC14000 fits perfectly in applications for battery charging, capacity monitoring, and data logging. The EPROM technology makes customization of application programs (battery characteristics, feature sets, etc.) extremely fast and convenient. The small footprint packages make this microcontroller based mixed signal device perfect for all applications with space limitations. Low-cost, low-power, high performance, ease of use and I/O flexibility make the PIC14000 very versatile in other applications such as temperature monitors/controllers.
Features:
The PIC14000 is a 28-pin device with these features: · 4K of EPROM · 192 bytes of RAM · 22 I/O pins The analog peripherals include: · 8 external analog input channels, two with level shift inputs · 6 internal analog input channels · 2 comparators with programmable references · A bandgap reference · An internal temperature sensor · A programmable current source In addition, the I2C serial port through a multiplexer supports two separate I2C channels. A special oscillator option allows either an internal 4 MHz oscillator or an external crystal oscillator. Using the internal 4 MHz oscillator requires no external components. The PIC14000 contains three timers, the Watchdog Timer (WDT), Timer0 (TMR0), and A/D Timer (ADTMR). The Watchdog Timer includes its own on-chip RC oscillator providing protection against software lock-up. TMR0 is a general purpose 8-bit timer/counter with an 8-bit prescaler. It may be clocked externally using the RC3/T0CKI pin. The ADTMR is intended for use with the slope A/D converter, but can also be used as a general purpose timer. It has an associated capture register which can be used to measure the time between events. An internal low-voltage detect circuit allows for tracking of voltage levels. Upon detecting the low voltage condition, the PIC14000 can be instructed to save its operating state then enter an idle state.
1.1
Family and Upward Compatibility
Code written for PIC16C6X/7X can be easily ported to the PIC14000 (see Appendix A).
1.2
Development Support
The PIC14000 is supported by a full-featured macro assembler, a software simulator, an in-circuit emulator, a low-cost development programmer and a full-featured programmer. A "C" compiler and fuzzy logic support tools are also available.
