BH67F5362A 개요

The Holtek Semiconductor BH67F5362A is a high-performance 8-bit RISC Flash microcontroller with an integrated 24-bit Delta-Sigma analog-to-digital converter and an LCD driver, engineered for high-precision measurement products such as electronic scales, blood pressure meters, clinical thermometers, and industrial meters. It supports a system clock up to 16 MHz delivering up to 0.25 µs instruction cycle at VDD = 5 V, and is housed in an LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch). Wide operating voltage from 1.8 V to 5.5 V at 8 MHz scales up to 3.3 V–5.5 V at 16 MHz, and the part integrates multi-programmable Flash program memory, RAM data memory, and true EEPROM for non-volatile calibration and serial-number storage.

A microcontroller with an integrated 24-bit Delta-Sigma ADC is part of the precision-measurement MCU category, which sits hierarchically within MCU -> microcontroller -> embedded controller -> semiconductor. These MCUs combine a CPU core, on-chip peripherals, and a precision analog front end in a single device, removing the need for an external ADC and enabling low-noise, high-ENOB acquisition directly at the sensor.

Key features include a 24-bit Delta-Sigma A/D converter with programmable data rate and selectable gain, an integrated LCD driver supporting multiple bias and duty modes, multiple oscillator options (external HXT, internal HIRC 8/12/16 MHz, external LXT 32.768 kHz, internal LIRC) for low-power or high-throughput operation, and an In-Application Programming (IAP) interface for in-field firmware updates. Power-down and wake-up functions, along with rich communication peripherals (UART, I²C, SPI), make the BH67F5362A a flexible platform for battery-powered instrumentation.

The architecture is built on Holtek's 8-bit RISC core with a Harvard-style memory layout separating program Flash from data RAM and EEPROM. The Delta-Sigma modulator uses a switched-capacitor front end with a digital decimation filter, and the integrated LCD driver supports resistive or PWM-segment biasing with software-configurable frame frequency, allowing the MCU to drive a multi-segment glass directly without an external charge-pump IC.

Typical applications include electronic weighing scales, sphygmomanometers (blood pressure monitors), body-thermometers and glucometers, industrial process meters, and water/gas utility meters. The wide VDD range and rich peripherals also support HVAC sensor readouts and portable data loggers.

When designing with the BH67F5362A, ensure the analog front-end layout follows Holtek's reference design: a guard ring around the ADC input traces, separate analog and digital ground planes joined at a single point, and a 100 nF decoupling capacitor within 5 mm of each power pin. Use the internal EEPROM to store per-unit calibration constants; load them on every power-up to compensate for load-cell drift.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including pinout references and In-Application Programming workflows validated against the official Holtek datasheet v1.10.

  • Integrated 24-bit Delta-Sigma ADC removes external analog front end (vs BH66F5362)
  • Cost-optimized within Holtek 24-bit A/D LCD MCU family (vs BH67F5372A)
  • True on-chip EEPROM for calibration data retention (vs BH67F5262)

설계 노트

Place a guard ring around the ADC input traces (AIN0+/AIN0-/VREF) and join analog and digital grounds at a single point near the AVSS pin. Place a 100 nF decoupling capacitor within 5 mm of every VDD/AVDD pin and a bulk 10 µF capacitor near the regulator output. This layout is mandatory for achieving the rated ENOB of the 24-bit Delta-Sigma ADC; without it, ENOB drops by 2–4 bits due to digital switching noise coupling into the analog front end.

Do not assume the on-chip voltage regulator is automatically configured for your VDD range. Per Holtek datasheet v1.10, fix the trim voltage at 3 V for application voltages 1.8 V–3.6 V and at 5 V for 3.3 V–5.5 V. Failing to set the correct trim voltage can cause ADC reference drift and increased current consumption. Always confirm the trim setting via the configuration register before production release.

Use the LXT 32.768 kHz crystal oscillator with the power-down / wake-up functions for battery-powered metering applications. With proper duty cycling the BH67F5362A achieves multi-year battery life on residential water and gas meters per the Holtek datasheet. Estimated: at 3 V supply, 1 µA average current in power-down with periodic ADC sampling every 30 s yields >5 years of operation from a single 2.4 Ah lithium thionyl chloride cell.
