93 / 136 page  2002 Microchip Technology Inc. DS39597B-page 91 PIC16F72 14.2 DC Characteristics: PIC16F72 (Industrial, Extended) PIC16LF72 (Industrial) DC CHARACTERISTICS Standard Operating Conditions (unless otherwise stated) Operating temperature -40°C ≤ TA ≤ +85°C for industrial -40°C ≤ TA ≤ +125°C for extended Operating voltage VDD range as described in DC Specification, Section 14.1. Param No. Sym Characteristic Min Typ† Max Units Conditions VIL Input Low Voltage I/O ports D030 with TTL buffer VSS — 0.15 VDD V For entire VDD range D030A VSS — 0.8V V 4.5V ≤ VDD ≤ 5.5V D031 with Schmitt Trigger buffer VSS — 0.2 VDD V D032 MCLR, OSC1 (in RC mode) VSS — 0.2 VDD V D033 OSC1 (in XT and LP mode) VSS — 0.3V V (Note 1) OSC1 (in HS mode) VSS — 0.3 VDD V (Note 1) VIH Input High Voltage I/O ports D040 with TTL buffer 2.0 — VDD V4.5V ≤ VDD ≤ 5.5V D040A 0.25 VDD + 0.8V — VDD V For entire VDD range D041 with Schmitt Trigger buffer 0.8 VDD — VDD V For entire VDD range D042 MCLR 0.8 VDD — VDD V D042A OSC1 (in XT and LP mode) 1.6V — VDD V (Note 1) OSC1 (in HS mode) 0.7 VDD — VDD V (Note 1) D043 OSC1 (in RC mode) 0.9 VDD — VDD V D070 IPURB PORTB Weak Pull-up Current 50 250 400 µAVDD = 5V, VPIN = VSS IIL Input Leakage Current (Notes 2, 3) D060 I/O ports —— ±1 µAVss ≤ VPIN ≤ VDD, Pin at hi-impedance D061 MCLR, RA4/T0CKI —— ±5 µAVss ≤ VPIN ≤ VDD D063 OSC1 —— ±5 µAVss ≤ VPIN ≤ VDD, XT, HS and LP osc configuration * These parameters are characterized but not tested. † Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested. Note 1: In RC oscillator configuration, the OSC1/CLKI pin is a Schmitt Trigger input. It is not recommended that the PIC16F72 be driven with external clock in RC mode. 2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages. 3: Negative current is defined as current sourced by the pin. |
