FAQ
What is the operating temperature range of the R5F21336TDFP#30?
The R5F21336TDFP#30 is rated for −40°C to +85°C ambient operation (D version), making it suitable for industrial environments where extended cold-start capability is required. This differs from the N version (e.g., R5F21336TNFP), which is limited to −20°C to +85°C. The R5F21336TDFP#30 maintains full functionality across this range, including data flash programming and ADC accuracy.
Does the R5F21336TDFP#30 support hardware LIN communication?
Yes, the R5F21336TDFP#30 integrates a dedicated hardware LIN module using Timer RA and UART0, enabling ISO 17987-compliant communication without external transceivers. Pins TRAO (P3_7) and TRAIO (P3_5) serve as LIN TX/RX, and the MCU handles protocol framing, checksum, and synchronization - reducing software load and improving timing reliability compared to bit-banged implementations.
How much data flash does the R5F21336TDFP#30 include, and what is its endurance?
The R5F21336TDFP#30 includes 4 KB of data flash organized as four 1 KB blocks, supporting background operation (BGO) for concurrent read/erase/write. Its specified endurance is 10,000 erase/write cycles per block, validated under VCC = 2.7–5.5 V. This enables reliable storage of calibration data, device configuration, or field-upgradable firmware segments without requiring external EEPROM.
What are the key low-power features of the R5F21336TDFP#30?
The R5F21336TDFP#30 offers wait mode (typ. 3.5 µA at 3.0 V) and stop mode (typ. 2.0 µA at 3.0 V), both retaining RAM contents and wake-up capability via INT pins or reset. It also includes selectable on-chip oscillators (high-speed adjustable, low-speed fixed) and voltage detection circuits - allowing dynamic clock gating and supply monitoring to extend battery life in portable applications without sacrificing responsiveness.
Can the R5F21336TDFP#30 perform capacitive touch sensing, and how many channels are supported?
Yes, the R5F21336TDFP#30 integrates a Sensor Control Unit supporting electrostatic capacitive touch detection across 18 channels: 3 system channels (CHxA, CHxB, CHxC) and 15 dedicated pins (CH0–CH14, plus CH15–CH17 mapped to P2_0–P2_2). This enables robust touch button, slider, or proximity sensing without external ICs - with built-in noise immunity and auto-calibration features documented in the R8C/33T Group hardware manual.
