PIC18F6723T-I/PT - 128KB Flash 8-Bit MCU | Microchip 64-TQFP
MPN: PIC18F6723T-I/PT ✓ NakahandaPIC18F6723T-I/PT Ulas
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory, volatile data memory and a range of on-chip peripherals such as timers, ADCs and communication interfaces. PIC18 devices belong to the broader 8-bit MCU category (hypernyms: microcontroller -> embedded controller -> semiconductor -> integrated circuit) and sit between simpler PIC16 parts and the 16-bit dsPIC/PIC24 families, balancing code density, peripheral richness and cost for mid-range embedded designs.
Key features of this part include 128 KB Flash organized as 64K x 16, an internal 8 MHz oscillator with PLL options, nanoWatt power management with multiple idle/sleep modes, a 10-bit/12-bit ADC with up to 12 channels, and the standard PIC18 instruction set with C-compiler-friendly architecture. The T suffix denotes tape-and-reel packaging; the I suffix indicates the industrial -40C to +85C operating temperature grade.
Typical applications are large low-power human-interface panels, USB peripherals, CAN-connected sensor nodes, industrial control with LIN/UART bridges, and consumer appliances requiring a rich mix of analog and digital I/O. For each of these use cases, the combination of 128 KB Flash and four independent serial ports removes the need for external memory or a companion communication chip.
When designing with this MCU, allocate the ADC acquisition time carefully when using high-impedance sources, and provide adequate decoupling on AVDD/AVSS to preserve 12-bit conversion linearity. Watch the absolute maximum VDD of 7.5 V during hot-plug events and respect the in-circuit debuggers' pin assignments when laying out the 64-TQFP footprint.

Talaan ng Disenyo
Place a 100 nF decoupling capacitor on each VDD/VSS pin pair (pins 12/13, 30/31, 60/61) within 5 mm of the package, and a single bulk 10 uF tantalum or ceramic capacitor on the main VDD rail. The PIC18F6723T-I/PT integrates nanoWatt sleep modes; switching to idle or sleep with peripherals disabled drops supply current below 10 uA, which is critical for battery-backed industrial nodes. Always power AVDD/AVSS even if the ADC is unused, and tie unused analog inputs to AVDD or AVSS to avoid floating-input leakage.
Route the crystal traces (OSC1/OSC2, pins 14/15) as short as possible (under 5 mm) and keep them on the top layer with a guard ground trace, since the 40 MHz fundamental or PLL-derived clocks drive harmonics that couple into the analog inputs. Provide a quiet analog ground island around AVSS/AVDD and join it to the digital ground at a single point under the IC body. Use USB differential pair routing with 90-ohm impedance and keep D+/D- matched within 150 mil.
Do not leave MCLR floating; the MCLR pin (pin 54) requires a 10 kohm pull-up to VDD for normal operation. Configure CONFIG3H to disable the internal MCLR if you wire MCLR to a low-impedance source. Watch the absolute maximum VDD of 7.5 V when the board is hot-plugged; add a TVS or series resistor on VDD for industrial installations with long cable harnesses that can inject transients.
For 12-bit ADC accuracy, source the analog signals through op-amp buffers with low output impedance (<100 ohm) so the 10 kSPS acquisition window can settle within 1 LSB. The ADC acquisition time is configured via ADCON3; for 5 V reference and 25C operation a typical minimum TACQ of 7.5 us is recommended. Use separate analog and digital power planes and keep switching signals away from the AN0-AN7 pins to avoid digital-induced ADC noise.
