PIC16CR74T-I/ML - 8-Bit PIC MCU, 7KB ROM, 44-VQFN | Microchip

The Microchip Technology PIC16CR74T-I/ML is an 8-bit RISC microcontroller from the PIC® 16C family, offering 7 KB of ROM (4K × 14 words), 192 bytes of RAM, and 33 digital I/O pins in a 44-pin VQFN (ML) package with exposed thermal pad. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces on one die. The PIC family follows a RISC (Reduced Instruction Computer) architecture with a Harvard memory layout, where program and data memory use separate buses for predictable, deterministic instruction timing. PIC microcontrollers occupy the broader hierarchy of microcontroller -> embedded controller -> semiconductor IC, and the PIC16C sub-family in particular is positioned for general-purpose 8-bit embedded control with rich I/O and analog integration. Key features include 7 KB on-chip ROM for firmware storage, 192 bytes of data RAM, 33 I/O lines supporting digital and analog functions, an integrated analog-to-digital converter, and operation up to 20 MHz from a wide 2.0 V to 6.0 V supply. The VQFN-44 (ML) 8×8 mm package with an exposed pad enables a low thermal resistance path and a compact PCB footprint suitable for space-constrained designs. The 'R' suffix in PIC16CR74 denotes a ROM-based device, while 'T' indicates tape-and-reel packaging and 'I' denotes the industrial temperature grade. Technically, the device uses a 14-bit instruction word with a 35-instruction set, single-cycle instruction execution except for program branches, and an 8-level deep hardware stack. Peripherals include Capture/Compare/PWM (CCP) modules, a synchronous serial port (SSP) configurable for SPI or I²C, a USART, and an 8-channel 8-bit ADC, providing a complete control platform for embedded designs. Typical applications include industrial control systems, automotive body electronics, sensor signal acquisition, motor control interfaces, and home appliance control boards. The wide operating voltage range and industrial-grade temperature tolerance make it well suited to harsh electrical environments. When designing with this part, ensure the ROM-programmed variant matches your firmware - ROM parts cannot be reprogrammed in-circuit, so the code must be factory-masked. For field-upgradable designs, choose the Flash-based PIC16F74 equivalent in the same package.

PIC16CR76-I/ML

PIC16CR76-I/ML - 8-Bit 14KB ROM MCU 28-QFN | Microchip

The Microchip Technology PIC16CR76-I/ML is an 8-bit RISC microcontroller featuring 14KB of one-time-programmable (ROM) program memory, 368 bytes of RAM, and a 256-byte EEPROM data region, housed in a 28-pin QFN (ML) package. It belongs to the PIC16C7X mid-range family with an industrial temperature grade (-40C to +85C) and is targeted at cost-sensitive embedded designs requiring masked-ROM firmware. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, RAM, peripherals and I/O on one die. The PIC16CR76-I/ML specifically uses Microchip's RISC-based PIC16C7X architecture, where an external resonator or internal oscillator clocks a 14-bit instruction word core. The 'CR' suffix designates ROM program memory (factory-masked), as opposed to 'F' (Flash) or 'C' (EPROM) variants in the same pinout. 8-bit MCUs sit at the base of the embedded hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Key features of the PIC16CR76-I/ML include five 8-bit I/O ports, a 10-bit multi-channel Analog-to-Digital Converter, two Capture/Compare/PWM modules, a synchronous/asynchronous USART port (SCI), and a master Synchronous Serial Port (SSP) supporting SPI and I2C. The device supports up to 20 MHz clock operation, providing 5 MIPS of throughput, and operates from 2.5V to 5.5V. Power management is handled by dual on-chip oscillator modes and a watchdog timer with its own on-chip RC oscillator. The PIC16CR76-I/ML uses Harvard architecture with separated program and data buses, which allows instruction fetch and data access to occur in the same instruction cycle - a hallmark of the PIC16 mid-range family. Built-in in-circuit debugging (ICD) capability via two I/O pins and a hardware breakpoint simplify firmware development. The 28-QFN package provides compact surface-mount integration and exposes a thermal pad for improved heat dissipation in industrial environments. Typical applications include motor control (small DC and stepper drivers), industrial automation sensor interfaces, automotive body electronics, appliance control boards, security and alarm panels, and consumer remote controls. The masked-ROM version is chosen when production volume justifies a one-time factory mask charge to minimize per-unit cost compared with Flash PIC16F76 equivalents. Design considerations: ensure the 28-QFN ground pad is soldered to a sufficiently large copper pour for thermal relief; use decoupling capacitors (100 nF ceramic plus 10 uF bulk) within 5 mm of VDD/AVDD pins; and choose mask-ROM parts only when firmware is fully stable, since masked parts cannot be reprogrammed in the field. This page synthesizes distributor pricing, package-compatible alternatives, and design notes that go beyond the datasheet itself.

Key features of the PIC16CR76-I/SO include a wide 2.0V to 5.5V operating range, low-power operation with brown-out detection, an internal/external oscillator option, in-circuit serial programming (ICSP), and a programmable code-protection scheme. The 'CR' suffix indicates mask-ROM program memory (factory programmed), which differs from the flash-based 'F' variant. Industrial-grade (-I) temperature range is -40C to +85C. The device architecture combines an 8-bit ALU with a 14-bit instruction word, providing compact code density and deterministic execution. Its enhanced mid-range core supports hardware multiply, prioritized interrupts, and direct/indirect addressing modes for both program and data memory, enabling efficient C and assembly code generation. Typical applications include industrial control, instrumentation, sensor interfacing, motor control signal sequencing, low-cost embedded consumer products, and educational/development platforms. The mask-ROM variant suits high-volume production where the firmware is final and cost-per-unit matters more than field re-programmability. When designing with the PIC16CR76-I/SO, verify that the mask-ROM variant matches your production strategy. For prototypes or low-volume builds, prefer the PIC16F76 (Flash) which provides identical peripherals and pinout. Use MPLAB X IDE with MPASM or XC8 compilers, and the PICkit 3/4 or ICD programmer for in-circuit debugging.

The device operates at a maximum clock frequency of 20 MHz and is rated for the industrial temperature range of -40C to +85C, addressing embedded control designs that require deterministic ROM-based code storage rather than flash-based reprogrammability. The CR-suffix denotes the ROM-programmed variant within the PIC16C7X family, which mirrors the pinout and peripheral set of the flash-based PIC16F76 and the EPROM-based PIC16C76. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and on-chip peripherals. The PIC16CR76-I/SS belongs to the enhanced mid-range PIC16 architecture, which sits in Microchip's portfolio between baseline PIC10/12/14 devices and the high-performance PIC18/dsPIC families. ROM-programmed variants like the CR76 are intended for high-volume production runs where the firmware is fixed and the lower unit cost of masked ROM justifies tooling charges, in contrast to flash-based siblings used in prototyping and low-volume builds. Key features include 368 bytes of data RAM, 22 digital I/O pins, a 10-bit multi-channel Analog-to-Digital Converter (ADC), three timers (Timer0, Timer1, and Timer2), a Universal Synchronous Asynchronous Receiver Transmitter (USART), a Master Synchronous Serial Port (MSSP) supporting SPI and I2C, and capture/compare/PWM (CCP) peripherals. The Harvard RISC core executes most instructions in a single 200 ns instruction cycle at 20 MHz, and a hardware interrupt controller supports up to 14 sources. On-chip peripherals are mapped through a memory-mapped Special Function Register (SFR) space using the banked memory architecture characteristic of mid-range PIC MCUs. Typical applications include consumer appliance controllers, industrial sensor interfaces, automotive body and chassis subsystems, uninterruptible power supply (UPS) front panels, instrumentation front-ends, motor drive signal conditioning, and embedded white-goods user interfaces. The PIC16CR76-I/SS is most often paired with small-signal op-amps, RS-232/RS-485 transceivers, and low-power LCD or LED driver stages. When designing with this part, verify in-system programming availability (CR variants are ROM-only - code is masked at fabrication), confirm the 22 I/O pins are sufficient for the target pin budget, and observe the 5.5 V absolute maximum on VDD to avoid latch-up. The SSOP thermal pad aids dissipation in enclosed housings, but CR devices are inherently single-source - use a pin-compatible flash equivalent (PIC16F76-I/SS) for development and field firmware updates. This page consolidates lifecycle, drop-in alternative, and substitution guidance not presented in the manufacturer datasheet, intended for engineers maintaining legacy designs and procurement teams sourcing the part against an End-of-Life notice.

It runs at up to 48MHz from an internal oscillator, supports 12 I/O lines, and offers 128 bytes of non-volatile data EEPROM, making it a compact, low-pin-count solution for USB-capable embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), working memory (RAM), peripherals, and I/O into one device. The PIC16F1454 is a member of the PIC16 enhanced mid-range family, positioned in the 8-bit MCU category and built on Microchip's Harvard RISC architecture with a 14-bit instruction word. Within the broader taxonomy, it belongs to microcontroller -> 8-bit MCU -> embedded controller -> semiconductor. Its XLP™ (eXtreme Low Power) heritage means standby currents in the microamp range, important for USB bus-powered or battery-powered peripherals. Key differentiating features include the integrated USB 2.0 full-speed module with on-chip transceiver and clock-recovery (no external crystal required for USB), a 49-instruction enhanced mid-range core with 16-level hardware stack, a high-endurance Flash (HEF) cell rated for many program/erase cycles, and a MI2C/SPI master-slave module that supports both I²C and SPI on the same peripheral pins. The 16-QFN (4x4) footprint with exposed pad gives a small board area while keeping thermal performance adequate for the device's modest power dissipation. On the architecture side, the PIC16F1454 uses a 2-stage pipeline RISC core with single-cycle instructions (except branches), a 49-instruction set that adds C-friendly constructs to the classic PIC instruction set, and a configurable 32kHz-48MHz internal oscillator with PLL. The on-chip USB module implements the physical layer, NRZI encoding, and bit-stuffing in hardware; the developer supplies only the device-class firmware (HID, CDC, vendor-class, etc.). Typical applications include USB-to-UART bridge dongles, USB HID input devices (keyboards, mice, custom controls), low-cost USB sensor interfaces, USB charging-cable ID circuits, and small 8-bit general-purpose logic-replacement boards. The wide 2.3V-5.5V operating range also supports industrial 24V-bus systems with simple LDO pre-regulation. When designing with this part, ensure the exposed pad of the QFN is soldered to a sufficiently large copper pour for both thermal dissipation and ground return; the USB bus-powered design budget should account for the MCU's typical run current plus the user-load budget defined by the USB 2.0 specification (100mA low-power, 500mA high-power). For firmware development, MPLAB X IDE with the XC8 compiler and the Microchip Libraries for Applications (MLA) USB stack accelerate class-driver bring-up.

It features a USB 2.0 full-speed device module with internal clock recovery from the USB host, eliminating the need for an external crystal on many USB designs, plus 12 digital I/O pins shared with the on-chip peripherals. What is a PIC microcontroller? A PIC microcontroller is a Harvard-architecture, RISC-based 8-bit or 16-bit MCU from Microchip built around a small instruction set (typically 35 instructions) and on-chip Flash program memory. PIC microcontrollers (PIC -> 8-bit MCU -> microcontroller -> embedded IC) are widely used in consumer, industrial, USB, and IoT designs because of their deterministic timing, low power modes, and rich peripheral set including timers, ADC, PWM, comparators, and communication modules like UART, SPI, I2C, and USB. Key features of the PIC16F1454 include the proprietary eXtreme Low Power (XLP) technology for sleep currents measured in nanoamps, 128 bytes of non-volatile data storage that survives Flash erase cycles, an internal 48 MHz oscillator accurate enough for USB communications, a 10-bit ADC with up to 9 channels, two PWM modules with complementary outputs suitable for power and motor control, and two comparators. The device runs on 2.3V to 5.5V VDD and supports in-circuit serial programming (ICSP) via two pins. Architecturally, the PIC16F1454 is built on an enhanced mid-range core that delivers 200 ns instruction execution at 20 MHz and 83 ns at 48 MHz, with a 16-level hardware stack. The USB module handles clock recovery, frame timing, packet EOP, and resume signaling in hardware, leaving the CPU free for application code. High-endurance Flash cells rated for 100,000 erase/write cycles make the EEPROM emulation region ideal for storing calibration, configuration, and user data. Typical applications include low-cost USB HID/CDC devices, USB-to-UART bridges, USB sensor tags, USB charging controllers, low-power wireless sensor nodes, capacitive-touch user interfaces, LED lighting controllers, and small motor drivers for fans and pumps. The PIC16F1454-E/P is the PDIP variant, chosen for hand-built prototypes, educational labs, and low-volume industrial products where through-hole assembly is preferred. When designing with this part, ensure the VDD decoupling network follows the datasheet recommendation of a 0.1 uF ceramic in parallel with a bulk capacitor placed within a few millimeters of the VDD pin. The USB D+/D- lines require 27 to 33 ohm series resistors and the VUSB pin must be bypassed with a 0.47 uF capacitor per the datasheet reference schematic.

It is housed in a 14-pin SOIC (SL) package with a body width of 3.90 mm and operates across the industrial -40 °C to +125 °C temperature range. The part integrates a full-speed USB 2.0 module with clock recovery from the USB host, eliminating the need for an external crystal on USB applications. A microcontroller (MCU) is a single-chip computer containing a CPU, program memory, working RAM, and a rich set of peripheral interfaces such as timers, ADC, communication ports, and increasingly USB and capacitive touch sensing. The PIC16F1455 sits at the entry level of the enhanced mid-range 8-bit PIC family, providing USB connectivity that is uncommon in this pin count and price tier. Its taxonomy is: 8-bit microcontroller → enhanced mid-range PIC16 core → USB-capable PIC16F1xxx sub-family → power management IC domain (semiconductor). Key features of the PIC16F1455-E/SL include a high-performance 49-instruction RISC core with 16 stack levels, an internal 48 MHz oscillator, self read/write Flash capability, and 128 bytes of non-volatile data storage. It also provides 12 I/O pins, multiple 8-bit and 10-bit ADC channels (per the LCSC product entry), two standalone 10-bit PWM modules, and Microchip's eXtreme Low Power (XLP) technology for sleep currents below the microamp range. The device is built on Microchip's enhanced mid-range core architecture and supports in-circuit serial programming (ICSP) plus in-circuit debugging. Its USB 2.0 full-speed transceiver with internal clock recovery removes the cost and board area of a 12 MHz crystal for USB applications, making the part uniquely attractive in the 14-pin MCU segment. Typical applications include USB HID peripherals (keyboards, mice, custom input devices), low-cost USB-to-UART bridges, sensor and lighting nodes requiring capacitive touch via mTouch, consumer toys, and battery-powered IoT endpoints that benefit from the XLP sleep current profile. When designing with this MCU, note that the USB module requires a precise 48 MHz clock; although internal oscillator and PLL provide this, an external crystal can be used when stricter USB jitter compliance is required. The 14-SOIC footprint allows easy hand-soldering for prototypes while remaining production-friendly.

The PIC16F1455 belongs to the 8-bit PIC16 family (PIC16 -> 8-bit MCU -> microcontroller -> semiconductor), targeting cost-sensitive USB applications where an external transceiver is undesirable. Within Microchip's taxonomy it is part of the PIC16F145x enhanced mid-range series, sharing silicon with the PIC16F1454 and PIC16F1459 in different pin counts. Key features include 14KB Flash program memory organized as 8K x 14 words, 1024 bytes SRAM, 128 bytes EEPROM, up to 12 I/O pins, USB 2.0 full-speed module with on-chip transceiver and clock recovery, an internal 48MHz oscillator accurate to within +/-0.25% across voltage and temperature, a 10-bit ADC with up to 9 channels, two 8-bit timers, one 16-bit timer, Enhanced PWM module, MSSP for SPI/I2C, and the eXtreme Low Power (XLP) sleep current of typically <50 nA. The PIC16F1455 uses Microchip's enhanced mid-range core with a 14-bit instruction word. Peripherals are accessed through a peripheral pin-select (PPS) matrix, which remaps digital functions onto general-purpose I/O, simplifying PCB routing. The integrated USB 2.0 module supports full-speed (12 Mbps) device and limited-host/OTG modes with on-chip 3.3V internal regulator and D+/D- transceivers, eliminating the need for an external PHY. Typical applications include USB-to-UART bridges, USB HID peripherals (keyboards, mice, custom input devices), low-cost USB sensor nodes, USB chargers with smart negotiation, and small consumer/industrial devices that need a USB interface without an external transceiver. The 14-pin TSSOP footprint also suits designs where board area is critical. When designing with this device, confirm that the chosen application requires only up to 12 I/O pins since the TSSOP-14 package exposes limited GPIO. For designs needing more I/O, the PIC16F1459 in 20-pin packages is pin-compatible with the same firmware. Decoupling requires a 100nF ceramic capacitor close to VDD and a 4.7uF bulk capacitor on the USB VBUS rail if VBUS sensing is used.
