product description

PIC18F2423/2523/4423/4523 8-Bit Microcontrollers Microchip's PIC18F microcontrollers are the most powerful 8-bit devices in Microchip's product line. The CAN, LIN and Ethernet functions included in this family are part of a complete range of peripherals to meet the needs of embedded applications and versions, using XLP (Extreme Low Power) technology for applications where power consumption is a key consideration. The PIC18F2420/2520/4420/4520 family of microcontrollers is based on Microchip's PIC18 architecture, offering a 31-level hardware stack and 75 instructions. These MCUs offer up to 10 MIPS, up to 32 kb of program memory, up to 1536 kb of RAM and 256 kb of data EEPROM. Onboard configurable oscillator. ### Microcontroller Features 40 MHz Maximum CPU Speed 75 Instructions - 83 Instructions Supported via Extended Instruction Set 31 Levels Hardware Stack Configurable Internal Oscillator - Selectable Frequency Range 8 mHz to 31 kHz 25 Input/Output Pins - PIC18F2423 /2523 Models 36 Input/Output Pins - PIC18F4423/4523 Models nanoWatt Technology Power On Reset (POR) Power On Timer (PWRT) Oscillator Start Timer (OST) Power Down Reset (BOR) Extended Watchdog Timer (WDT) ) High-Voltage/Low-Voltage Detect (HLVD) Module In-Circuit Serial Programming (ICSP) In-Circuit Debug (ICD) ### Peripherals 12-Bit Analog-to-Digital Converter (ADC) - PIC18F2423/2523 Models 10-Channel; PIC18F4423/4523 13 Channels One Enhanced Capture, Compare, PWM Module - PIC18F4423/4523 Models Only Capture, Compare, PWM Module - PIC18F2423/2523 Models x 2, PIC18F4423/4523 Models x 1 Two Comparators One 8-Bit Timer Three 16-Bit Timing Master Synchronous Serial Port (MSSP) Module with SPI and I2C Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) ### PIC18 Microcontrollers
