Description

The PIC18F452-I/L devices come in 28-pin and 40/44-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.An overview of features is shown in Table 1-1.

Features of the PIC18F452-I/L are:(1)High current sink/source 25 mA/25 mA; (2)Three external interrupt pins; (3)Timer0 module: 8-bit/16-bit timer/counter with 8-bit programmable prescaler; (4)Timer1 module: 16-bit timer/counter ; (5)Timer2 module: 8-bit timer/counter with 8-bit period register (time-base for PWM); (6)Timer3 module: 16-bit timer/counter ; (7)Secondary oscillator clock option - Timer1/Timer3; (8)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; (9)Master Synchronous Serial Port (MSSP) module, Two modes of operation:- 3-wire SPI? (supports all 4 SPI modes)- I2C Master and Slave mode.

The absolute maximum ratings of the PIC18F452-I/L can be summarized as:(1)Ambient temperature under bias:-55°C to +125°C; (2)Storage temperature:-65°C to +150°C; (3)Voltage on any pin with respect to VSS (except VDD, MCLR,and RA4):-0.3V to (VDD + 0.3V); (4)Voltage on VDD with respect to VSS :-0.3V to +7.5V; (5)Voltage on MCLR with respect to VSS (Note 2):0V to +13.25V; (6)Voltage on RA4 with respect to Vss:0V to +8.5V; (7)Total power dissipation (Note 1):1.0W; (8)Maximum current out of VSS pin :300 mA; (9)Maximum current into VDD pin:250 mA; (10)Input clamp current, IIK (VI < 0 or VI > VDD):±20 mA; (11)Output clamp current, IOK (VO < 0 or VO > VDD):±20 mA; (12)Maximum output current sunk by any I/O pin:25 mA; (13)Maximum output current sourced by any I/O pin:25 mA; (14)Maximum current sunk by PORTA, PORTB, and PORTE (Note 3) (combined):200 mA; (15)Maximum current sourced by PORTA, PORTB, and PORTE (combined):200 mA; (16)Maximum current sunk by PORTC and PORTD (Note 3)(combined):200 mA; (17)Maximum current sourced by PORTC and PORTD (Note 3) (combined):200 mA.
