PIC24FV08KM101-E/P - 8KB Flash 16-bit MCU, 20-PDIP | Microchip
MPN: PIC24FV08KM101-E/P ✓ Hoạt độngPIC24FV08KM101-E/P Tóm tắt
A microcontroller is a single integrated circuit that combines a processor core, program memory, data memory, and configurable I/O peripherals on one die, enabling compact, deterministic embedded control. Within the system hierarchy, the PIC24FV08KM101 sits under the PIC24F family of 16-bit Flash microcontrollers, itself part of the broader 16-bit MCU category, which bridges 8-bit PIC MCUs and 32-bit ARM Cortex-M devices. The "F" denotes Flash program memory; the "V" indicates the wide-voltage variant; the "KM" series adds Configurable Logic Cell (CLC), Capture/Compare/PWM modules, and 12-bit ADC support; and "101" identifies the 8 KB Flash / 1 KB RAM memory profile.
Key features include a 16-channel 10-bit or 12-bit Analog-to-Digital Converter, multiple Capture/Compare/PWM (MCCP/SCCP) peripherals, configurable logic cells, comparators, and a 512-byte EEPROM emulation block in Flash. Connectivity is provided through I²C, SPI, UART/USART, IrDA, and LINbus interfaces. The nanoWatt XLP architecture supports multiple low-power Sleep and Idle modes for battery-driven designs.
Internally the device uses a modified Harvard architecture with a 16-bit data path, hardware multiply/divide, and a 16-element working register array. The wide 2.0 V to 5.5 V supply range allows direct interface with both 3.3 V and 5 V sensors and logic families without level translation, and the 12-bit ADC with multiple S&H or I2 input channels supports mixed-signal sensing tasks.
Typical applications include low-power sensor nodes, industrial control peripherals, automotive body electronics (LIN nodes), USB/HID accessories using the PIC24F USB-capable family, LED lighting controllers, and battery-charging front ends. The 20-pin PDIP package is especially suited for through-hole prototyping, educational platforms, and pre-production builds where easy rework is required.
When designing with the PIC24FV08KM101-E/P, decouple VDD with a 100 nF ceramic capacitor placed as close to the pin as possible, and add a 10 µF bulk capacitor if the supply traces are long. Confirm that your chosen supply voltage remains within the 2.0 V–5.5 V specification across temperature, because the V variant tolerates 5 V operation only because of its internal charge-pump design.

Ứng dụng tiêu biểu
PIC24FV08KM101-E/P phù hợp cho 7 Áp dụngs: Low-Power IoT Sensor Node, Industrial Control Peripheral (LIN Bus Node), Automotive Body Electronics, LED Lighting Controller, USB/HID Accessory Controller, Battery Charger Front-End, Educational / Prototyping Platform.
Low-Power IoT Sensor Node
The PIC24FV08KM101-E/P suits battery-driven wireless sensor endpoints thanks to its nanoWatt XLP idle currents, 2.0 V–5.5 V supply range that works directly from a single Li-ion cell or 2xAA pack, and 16-channel 12-bit ADC that digitizes multiple analog sensors without an external mux. Its 8 KB Flash is enough for a small RTOS-less state machine or a lightweight MQTT-SN over UART bridge, and the configurable logic cell (CLC) lets engineers replace a few external gates with on-chip logic. Compared with a discrete 8-bit MCU plus op-amp front end, this part consolidates the analog chain on one die.

Industrial Control Peripheral (LIN Bus Node)
The PIC24FV08KM101-E/P is a strong fit for industrial peripherals thanks to its on-chip LINbus hardware and 2.0 V–5.5 V operation that tolerates noisy 24 V-derived rails after regulation. The 32 MHz CPU and 16 MIPS throughput handle LIN 2.x protocol stacks plus diagnostic UDS routines without offloading to a transceiver MCU. The 20-pin PDIP package simplifies hand-soldered prototypes on bench instrumentation, while the 16-channel 12-bit ADC reads actuator feedback directly. Compared with discrete LIN SBCs, this single-chip solution reduces BOM cost and PCB area.

Automotive Body Electronics
The PIC24FV08KM101-E/P targets automotive body modules including seat controllers, mirror adjusters, and ambient lighting nodes. Its -40 °C to +125 °C extended temperature grade survives under-hood thermal stress, and the 32 MHz 16 MIPS core handles LIN/K-Line communication plus PWM-driven actuators with deterministic latency. The wide 2.0 V–5.5 V supply range accepts the 12 V battery rail after a single LDO, eliminating the need for a pre-regulator. Compared with an AEC-Q100 qualified dsPIC, this part saves cost while remaining inside the E-grade temperature envelope.
Được đề xuất
LED Lighting Controller
The PIC24FV08KM101-E/P drives LED lighting strings using its on-chip Capture/Compare/PWM (MCCP/SCCP) modules to generate accurate current-mode PWM at high resolution. Its 16-channel 12-bit ADC monitors photodiodes for ambient feedback and closed-loop dimming, while CLC blocks implement hardware fault detection that offloads CPU overhead. The wide 2.0 V–5.5 V supply operates from a single 3.3 V or 5 V rail, simplifying power-tree design. Compared with a 555-timer-based analog driver, this MCU enables networked, addressable, and dynamically-tuned lighting.
Được đề xuất
USB/HID Accessory Controller
Although the PIC24FV08KM101-E/P itself lacks native USB, it pairs cleanly with an external USB-serial bridge to implement USB/HID accessories like custom keyboards, mice, or HID-class game controllers. The 16 MIPS core handles HID report descriptor parsing and debounce logic in firmware, while the on-chip CLC blocks accelerate matrix-scanning without CPU wake-ups. The 20-pin PDIP footprint is friendly to hobbyist and small-batch products. Compared with a dedicated USB MCU, this part trades native USB for BOM flexibility and a simpler supply tree.
Được đề xuất
Battery Charger Front-End
The PIC24FV08KM101-E/P serves as a battery-charger front-end controller thanks to its 12-bit ADC that accurately measures battery voltage and charge current, plus PWM peripherals that drive a MOSFET switch-mode stage. The 2.0 V–5.5 V supply is compatible with single-cell Li-ion, LiFePO4, and NiMH packs, while the nanoWatt XLP modes let the controller sleep when not actively managing charge cycles. Compared with analog charger ICs, this MCU-based approach allows chemistry reconfiguration via firmware and adaptive temperature profiling.
Được đề xuất
Educational / Prototyping Platform
The PIC24FV08KM101-E/P in a 20-pin PDIP is a classic platform for university embedded-systems courses, hobbyist projects, and engineering training. Its through-hole footprint is breadboard-friendly, eliminating SMD rework, and the 8 KB Flash / 1 KB RAM is large enough for representative 16-bit exercises (PWM, ADC, UART) without overwhelming a beginner. MPLAB X IDE + XC16 compiler are free, and the PICkit programmer/debugger interface is built into the part. Compared with a 32-bit Cortex-M board, this part has a simpler peripheral set that keeps introductory labs focused.

Ghi chú thiết kế
Place a 100 nF decoupling capacitor as close as physically possible to the VDD pin (pin 6), with a 10 uF bulk capacitor on the same supply trace if the source impedance is non-trivial. The 2.0 V–5.5 V wide-voltage range allows direct operation from a single Li-ion cell or 5 V rail, but ensure VDD never exceeds 5.5 V including load-dump transients in automotive environments.
Although the PIC24FV08KM101-E/P draws tens of mA under load, in a 20-pin PDIP package heat dissipation is generally not a concern at room temperature. At 32 MHz and 5 V with all peripherals active, package dissipation is well below 100 mW; no heatsink is required. For high ambient temperatures near +125 C, verify the maximum junction temperature against the package's theta_JA value in [DATA_NEEDED: theta_JA from datasheet].
Keep the crystal or external clock traces short and symmetric (OSC1 and OSC2, pins 8–9), and route them away from switching nodes. For through-hole PDIP prototypes, allow generous creepage between the analog inputs (AN0–AN14) and the digital I/O on the same package to avoid capacitive coupling. Use a ground plane on the bottom layer to provide a clean reference for the 12-bit ADC.
Estimated: enabling the ADC without adequate acquisition time causes noisy conversions; ensure the ACQT bits in AD1CON3 match the analog source impedance (typically >1 us for 5 kohm sources). Never program the on-chip LDO/brown-out reset incorrectly for 5 V operation - the V variant supports 5 V directly, but the F variant (PIC24F08KM101) does not exceed 3.6 V. Always use the latest errata (DS80000567-class) when designing firmware around peripheral behavior.
