DS39747B is the data sheet of PIC24FJ128GA series released by Microchip Technology Inc., which introduces the features and characteristics of the series products.
The PIC24FJ128GA family is a line of general‑purpose 16‑bit flash microcontrollers featuring a modified Harvard architecture, up to 16 MIPS at 32 MHz, and a wide operating voltage range of 2.0 V to 3.6 V. It includes on‑chip peripherals such as a 10‑bit 16‑channel ADC, multiple UARTs, SPI, I²C, timers, and a real‑time clock/calendar.
The datasheet provides detailed information on memory organization, flash program characteristics, power‑saving modes, pin configurations for 64‑, 80‑ and 100‑pin TQFP packages, and electrical specifications. It also outlines code‑protection statements and warranty limitations.
| CPU performance | Up to 16 MIPS @ 32 MHz |
|---|---|
| Operating voltage | 2.0 V to 3.6 V |
| Flash endurance | 1000 erase/write cycles (typical) |
| Flash retention | 20 years (typical) |
| ADC resolution and speed | 10‑bit, up to 16 channels, 500 ksps |
| UART capabilities | RS‑232, RS‑485, LIN 1.2, IrDA support |
Microchip states that code protection does not guarantee the product is unbreakable and that no manufacturer can guarantee absolute security.
The UART modules support RS‑232, RS‑485, LIN 1.2, and IrDA with on‑chip hardware encoding/decoding.
The ADC provides up to 16 analog input channels.
