MICROCHIP PIC14000-04/SP

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.

• 4K of EPROM
• 192 bytes of RAM
• 8 external analog input channels, two with level shift inputs
• 6 internal analog input channels
• A bandgap reference
• An internal temperature sensor
• A programmable current source
• 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)
• 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
• 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
