PIC16F88-I/P Microchip Can Replace The Programming Program PIC16F88 88-i/p

datasheet

Low-power modes: RC_RUN allows the core and
peripherals to be clocked from the INTRC, while
SEC_RUN allows the core and peripherals to be
clocked from the low-power Timer1. Refer to
Section 4.7 “Power-Managed Modes” for
further details.
• Internal RC oscillator with eight selectable
frequencies, including 31.25 kHz, 125 kHz,
250 kHz, 500 kHz, 1 MHz, 2 MHz, 4 MHz and
8 MHz. The INTRC can be configured as a
primary or secondary clock source. Refer to
Section 4.5 “Internal Oscillator Block” for
further details.
• The Timer1 module current consumption has
been greatly reduced from 20 A (previous PIC16
devices) to 1.8 A typical (32 kHz at 2V), which is
ideal for real-time clock applications. Refer to
Section 7.0 “Timer1 Module” for further details.
• Extended Watchdog Timer (WDT) that can have a
programmable period from 1 ms to 268s. The
WDT has its own 16-bit prescaler. Refer to
Section 15.12 “Watchdog Timer (WDT)” for
further details.
• Two-Speed Start-up: When the oscillator is
configured for LP, XT or HS Oscillator mode, this
feature will clock the device from the INTRC while
the oscillator is warming up. This, in turn, will
enable almost immediate code execution. Refer
to Section 15.12.3 “Two-Speed Clock Start-up
Mode” for further details.
• Fail-Safe Clock Monitor: This feature will allow the
device to continue operation if the primary or
secondary clock source fails by switching over to
the INTRC.
• The A/D module has a new register for PIC16
devices named ANSEL. This register allows
easier configuration of analog or digital I/O pins.
