HA1835P Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the HA1835P is -40°C to +85°C, although it can withstand storage temperatures from -55°C to +125°C.

  • To ensure a stable and reliable power supply, it's recommended to use a high-quality power supply with a low ripple voltage (less than 100mV) and a sufficient current capacity (at least 1.5A). Additionally, decoupling capacitors should be used to filter out noise and voltage spikes.

  • The HA1835P supports a maximum clock frequency of 16.78 MHz, although it can be operated at lower frequencies depending on the specific application requirements.

  • The HA1835P's internal ROM can be programmed using a dedicated programmer or a development environment such as Hitachi's own development tools or third-party tools like Keil µVision. The programming process typically involves creating a hex file, connecting the programmer to the HA1835P, and uploading the code to the device.

  • The HA1835P offers several improvements over the HA1834P, including a higher clock frequency, increased ROM capacity, and additional peripherals such as a UART and a timer. The HA1835P also has a lower power consumption and improved noise immunity compared to the HA1834P.
