Description
These device PIC18C252 come in 28-pin and 40-pin packages. The 28-pin devices do not have a Parallel Slave Port (PSP) implemented and the number of Analog-toDigital (A/D) converter input channels is reduced to 5.
- High current sink/source 25 mA/25 mA
- Three external interrupt pins
- Timer0 module: 8-bit/16-bit timer/counter with 8-bit programmable prescaler
- Timer1 module: 16-bit timer/counter
- Timer2 module: 8-bit timer/counter with 8-bit period register (time-base for PWM)
- Timer3 module: 16-bit timer/counter
- Secondary oscillator clock option – Timer1/Timer3
- Two Capture/Compare/PWM (CCP) modules. CCP pins that can be configured as: – Capture input: capture is 16-bit, max. resolution 6.25 ns (TCY/16) – Compare is 16-bit, max. resolution 100 ns (TCY) – PWM output: PWM resolution is 1- to 10-bit. Max. PWM freq. @: 8-bit resolution = 156 kHz 10-bit resolution = 39 kHz
- Master Synchronous Serial Port (MSSP) module. Two modes of operation: – 3-wire SPI™ (supports all 4 SPI modes) – I2C™ master and slave mode
- Addressable USART module: – Supports interrupt on Address bit
- Parallel Slave Port (PSP) module Pin Diagrams Analog Features:
- Compatible 10-bit Analog-to-Digital Converter module (A/D) with: – Fast sampling rate – Conversion available during SLEEP – DNL = ±1 LSb, INL = ±1 LSb
- Programmable Low Voltage Detection (LVD) module – Supports interrupt-on-low voltage detection
- Programmable Brown-out Reset (BOR) Special Microcontroller Features:
- Power-on Reset (POR), Power-up Timer (PWRT) and Oscillator Start-up Timer (OST)
- Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation
- Programmable code protection
- Power saving SLEEP mode
- Selectable oscillator options including: – 4X Phase Lock Loop (of primary oscillator) – Secondary Oscillator (32 kHz) clock input
- In-Circuit Serial Programming (ICSP™) via two pins CMOS Technology:
- Low power, high speed EPROM technology
- Fully static design
- Wide operating voltage range (2.5V to 5.5V)
- Industrial and Extended temperature ranges
- Low power consumption
