AVR32DA28-I/SO

AVR32DA28-I/SO - 8-bit AVR DA MCU, 32KB Flash, 28-SOIC | Microchip

The Microchip Technology AVR32DA28-I/SO is an 8-bit AVR® DA family microcontroller with 32 KB of Flash, 4 KB of SRAM, and 512 bytes of EEPROM, running at up to 24 MHz across the full 1.8V to 5.5V supply range, housed in a 28-pin SOIC package. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working memory (SRAM), EEPROM, and a rich set of peripherals. The AVR® CPU belongs to a RISC architecture family known for deterministic instruction timing, single-cycle register access, and a mature toolchain (MPLAB X, Atmel Studio, and the Arduino-compatible DxCore core). In the broader taxonomy: AVR® DA -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The 1.8V to 5.5V supply range means the device can run directly from a single Li-ion cell or a regulated 3.3V / 5V rail, simplifying power-tree design. Key features include the hardware multiplier for fast arithmetic, an Event System for inter-peripheral signalling without CPU intervention, intelligent analog peripherals (12-bit ADC, three comparators, three zero-cross detectors, a DAC), capacitive touch (PTC) hardware, six U(S)ARTs, two SPI, and TWI (I²C-compatible). The 28-SOIC (I/SO) variant offers the largest pin count of the SO-package options and provides ample GPIO for keypad, segment-display, and mixed-signal front-ends. Internally, the AVR® DA uses a pipelined Harvard bus: separate Flash and SRAM buses let the CPU fetch instructions and read/write data in the same cycle. The 24 MHz clock, hardware multiplier, and zero-wait-state Flash fetch yield roughly 1 MIPS per MHz, so the part delivers up to ~24 MIPS. The integrated Core Independent Peripherals - Event System, CCL (Configurable Custom Logic), and peripheral touch controller - let complex timing and control tasks run with zero CPU load. Typical applications include capacitive touch human-machine interfaces (HMI), white-goods and small-appliance motor control, LED lighting controllers, sensor hubs with on-chip ADC, and battery-powered IoT nodes. The AVR® DA family is a popular modern replacement for legacy ATmega328P designs that need more Flash, real-time control, and touch capability without migrating to ARM. When designing with the AVR32DA28-I/SO, ensure the ICSP/PDI programming header follows the 6-pin AVR ISP convention with the MCLR pull-up sized for your VDD rail (typically 10 kΩ). Decouple VDD with a 100 nF X7R ceramic placed within 3 mm of each VDD pin, and add a 4.7 µF bulk capacitor near the AVCC pin to keep the ADC reference stable.

AX58100LT

AX58100LT - 2/3-Port EtherCAT Slave Controller | ASIX

The ASIX Electronics AX58100LT is a 2/3-port EtherCAT Slave Controller (ESC) with two integrated Fast Ethernet PHYs, operating from a 3.3V supply and packaged in an 80-pin LQFP-EP (10x10 mm). It implements the EtherCAT slave protocol in hardware and exposes 2 or 3 PHY ports plus digital host interfaces (SPI / host bus) to an external MCU, making it one of the most integrated single-chip ESCs in its class. An EtherCAT Slave Controller is a specialized industrial Ethernet IC that handles the EtherCAT protocol (a deterministic real-time Ethernet standard originally developed by Beckhoff and standardized by the EtherCAT Technology Group) without burdening the host CPU. The EtherCAT protocol itself falls under the broader hierarchy of industrial fieldbuses -> real-time Ethernet -> industrial communication IC -> semiconductor. The "slave" role means the device sits on the bus as a node that processes the EtherCAT datagram on the fly as it traverses each port, in contrast to an EtherCAT master which orchestrates the network. The AX58100LT integrates two 100BASE-TX Fast Ethernet PHYs directly on-die, eliminating the need for external PHY chips and reducing BOM cost, PCB area, and signal-integrity complexity for servo drives, distributed I/O, and sensor modules. With 100 Mbit/s full-duplex ports, it supports standard EtherCAT cycle times down to the 12.5 us micro-period range and the typical 1 ms motion-bus update rate. The industrial-grade -40C to +105C operating range suits it for servo, motion control, and factory automation deployments. Typical applications include EtherCAT servo motor drives, decentralized digital I/O modules, EtherCAT sensor interfaces, robotic joint controllers, EtherCAT junction or branch modules, and other industrial-automation nodes. The STM32F303RE host reference design published by ST validates AX58100LT for FOC (field-oriented control) servo loops and points designers toward proven firmware stacks. When designing with the AX58100LT, ensure the 80-pin LQFP-EP exposed pad is soldered with sufficient thermal via arrays to dissipate internal PHY power, and route the differential MDI pairs as 100-ohm differential controlled-impedance traces. The host MCU should run an ASIX-supported EtherCAT slave stack (e.g., SOES or SSC ported to the chosen MCU) to maximize bus conformance. This page synthesizes distributor pricing, LQFP-80 drop-in alternatives, and practical industrial-board design notes not found in the raw manufacturer datasheet, giving the BOM engineer a complete procurement and design entry point for EtherCAT nodes built around the AX58100LT.

The device is packaged in a 1020-ball FCPBGA (33x33 mm) and is the encrypted, 0-105C temperature-grade variant. The SoC is built on a 64-bit PowerPC e6500 architecture and is targeted at LTE-Advanced (LTE-A) and small-cell base-station designs where heterogeneous compute density matters. A heterogeneous SoC combines CPU, DSP, and hardware accelerator blocks on a single die, allowing baseband processing, L2/L3 protocol stack execution, and acceleration offload to run concurrently without crossing chip boundaries. The B4420 belongs to the QorIQ Qonverge family, itself a sub-family of the QorIQ communications processors, which in turn sits within the broader Power Architecture embedded microprocessor category. This hierarchy - B4420 -> QorIQ Qonverge -> QorIQ -> PowerPC -> communications processor -> microprocessor - reflects how NXP positioned the device for carrier-grade wireless. Key differentiating features include pin- and code-compatibility with the B4860 macrocell SoC, allowing OEMs to reuse a single hardware design and scale software between macrocell and metrocell deployments. The integrated MAPLE-B3 hardware accelerator performs forward-error-correction and turbo decoding at data rates required for 3G/4G modems. Hardware-accelerated security (encrypted variant) protects boot images and runtime code, while 0 to 105C operation suits outdoor base-station enclosures. The B4420 also supports legacy 2G/3G radio access networks, enabling migration paths from existing BTS platforms. Architecture-wise, the SoC combines dual-threaded PowerPC e6500 cores with their out-of-order execution pipeline, dual StarCore SC3900 VLIW DSP cores optimized for vector DSP workloads, and the MAPLE-B3 coprocessor block. A coherent fabric ties all cores to the shared L2/L3 memory subsystem and the high-speed SerDes interfaces. This contrasts with pure-DSP or pure-CPU SoCs that require external glue logic to balance compute loads. Typical applications include LTE small-cell (picocell / microcell / metrocell) base stations, 3G/HSPA+ Node B platforms, multi-standard radio access network (RAN) nodes, and other wireless infrastructure that combines CPU control plane, DSP modem firmware, and forward-error-correction hardware offload. The pin/code compatibility with B4860 also makes B4420 attractive for OEM designs that must scale capacity. A primary design consideration is the high 1020-ball FCPBGA package and 33x33 mm footprint, which demands a multilayer PCB (typically 10+ layers) with controlled-impedance SerDes routing, careful power-rail decoupling, and an experienced assembly flow. Engineers should validate thermal headroom at 105C ambient using the manufacturer's reference design and follow the B4420 Hardware Specifications document for signal-integrity guidelines.

BA728N

BA728N - Dual Op-Amp, 3-18V, Single Supply | ROHM

The ROHM BA728N is a dual independent operational amplifier IC featuring internal phase compensation, designed for general-purpose analog signal conditioning. The device integrates two op-amps in an 8-pin SIP package (Single In-line Package), with each amplifier providing standard open-loop gain, internal compensation, and a wide common-mode input range that includes the negative rail when powered from a single positive supply. What is a dual operational amplifier? A dual operational amplifier (dual op-amp) is an integrated circuit that combines two independent op-amp channels in a single package, sharing only the power and ground pins. Dual op-amps belong to the linear IC family, which itself sits within the broader category of analog signal-conditioning semiconductors. They are fundamental to almost every analog PCB, providing gain, buffering, filtering, and comparison functions at low cost and low power. Key features of the BA728N include: a single-supply operating voltage of 3V to 18V (or dual ±1.5V to ±9V), low power consumption typical of the BA728 family, pin configuration identical to the industry-standard 8-pin general-purpose op-amp outline, internal phase compensation (no external compensation capacitor required), and high common-mode input range that includes the negative supply rail when used in single-supply mode. The internal architecture is a classic bipolar transistor design with on-chip frequency compensation, eliminating the need for external compensation capacitors. This makes the BA728N a true drop-in functional equivalent to legacy 8-pin dual op-amps such as the LM358 / NJM4558 / BA4558 family, with the same DC characteristics but at a lower quiescent current and with ROHM's signature wide single-supply range. Typical applications include active filters, transducer signal conditioning, comparator circuits, DC gain blocks, audio pre-amplifiers, and general-purpose analog signal chains in consumer, industrial, and hobby electronics. Its pin-compatibility with the BA728 / BA728F variants (which differ only in mechanical package) allows designers to substitute across mechanical configurations without PCB changes. When designing with the BA728N, observe the absolute maximum supply rating of 18V (single supply) or ±9V (dual supply), place a 0.1 µF decoupling capacitor close to VCC+ pin, and avoid output short circuits to ground or either rail. The exposed lead frame (SIP package) limits mounting to through-hole assemblies only. This page synthesizes datasheet specifications, distributor pricing (as of 2026-10-05), pin-compatible alternatives, and practical design notes to help engineers select and apply this dual operational amplifier.
