DescriptionThe PIC18LF4321-I/ML is designed as one kind of high-performance, enhanced flash microcontroller that introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications. This device contains circuitry to prevent clocking "glitches" when switching between clock sources and when it executes a SLEEP instruction, the system is switched to one of the power managed modes, depending on the state of the IDLEN and SCS1:SCS0 bits of the OSCCON register.
Features of the PIC18LF4321-I/ML are:(1)High current sink/source 25 mA/25 mA; (2)Three external interrupts; (3)Compatible 10-bit, up to 13-channel Analog-to-Digital Converter module (A/D) with programmable acquisition time; (4)Dual analog comparators; (5)Addressable USART module: - RS-232 operation using internal oscillator block (no external crystal required); (6)Timer1 Oscillator: 1.1 uA, 32 kHz, 2V; (7)Watchdog Timer: 2.1 uA; (8)Two-Speed Oscillator Start-up; (9)100,000 erase/write cycle Enhanced Flash program memory typical; (10)1,000,000 erase/write cycle Data EEPROM memory typical; (11)Flash/Data EEPROM Retention: > 40 years; (12)Self-programmable under software control; (13)Priority levels for interrupts; (14)8 x 8 Single-Cycle Hardware Multiplier.
The absolute maximum ratings of the PIC18LF4321-I/ML 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: 0 V to +13.25 V;(6)Voltage on RA4 with respect to VSS: 0V to +8.5V;(7)Total power dissipation: 1.0 W;(8)Maximum current out of VSS pin: 300 mA;(9)Maximum current into VDD pin: 250 mA;(10)Maximum current sourced by all ports: 200 mA.
