R5F104BCANA#U0 - RL78/G14 32KB 32MHz 16-bit MCU | Renesas
MPN: R5F104BCANA#U0 ✓ Hoạt độngR5F104BCANA#U0 Tóm tắt
An RL78 microcontroller is a 16-bit CISC architecture developed by Renesas as a successor to the 16-bit 78K and R8C families. The RL78 core combines high code density, fast interrupt response, and an ultra-low-power design philosophy: a hierarchical taxonomy places it as RL78 -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Compared with 32-bit Cortex-M parts, RL78 typically delivers 30-50% lower active current per MHz and standby currents in the microamp range, making it ideal for battery-powered and energy-harvesting designs.
Key differentiating features of the R5F104BCANA#U0 include the RL78 CPU running up to 32 MHz (with 1.58 DMIPS/MHz throughput), on-chip debugging via single-wire TOOL0, multi-function timer array (TAU) supporting PWM, capture, and encoder input for motor control, a 10-bit successive-approximation ADC, multiple serial interfaces (CSI/UART/Simple I2C), and a wide 1.6V to 5.5V operating voltage range. The device supports the on-chip debug and serial programming modes accessed through dedicated TOOL0 and RESET pins, enabling in-circuit firmware updates without external programmers.
The R5F104BCANA#U0 is engineered around the RL78's three power-management modes (RUN, HALT, STOP) and an Snooze mode that lets peripherals run while the CPU sleeps, drawing as little as 0.5 uA in STOP with RTC retention. This architecture makes it well-suited for mains-powered appliances running from a small DC-DC supply and battery-operated portable instruments that must meet IEC 62368-1 standby budgets.
Typical applications include small BLDC/PMSM motor control (fans, pumps, appliance drives), energy metering (single-phase power/electricity meters, water/gas meters), industrial sensor nodes, IoT edge devices, and user-interface or HMI front panels. The HWQFN-32 footprint also allows compact PCB layouts where board space is at a premium.
When designing with this device, ensure the exposed pad (EP) is soldered to a sufficient copper pour on the top or bottom layer to meet the thermal resistance (theta_JA) of the package. Use Renesas' e2 studio IDE and the RL78 GCC or CC-RL toolchain for firmware development; the on-chip debug interface works with the E2 or E2-Lite emulator for real-time trace and flash programming.

Bảo phân biệt quan trọng
- Industry-leading low active current per MHz for the 16-bit class (vsGeneric 32-bit Cortex-M0 MCU at equivalent MHz)
- Single-wire TOOL0 on-chip debug (vsOlder 78K0 parts requiring 4-wire debug)
- Wide 1.6V to 5.5V supply in HWQFN-32 (vsTypical 32-bit MCU requiring 3.3V LDO)
Ghi chú thiết kế
Estimated: The HWQFN-32 exposed pad must be soldered to a continuous copper pad on the top or bottom layer to keep theta_JA within datasheet limits. Recommended pad is at least 3.5x3.5 mm with thermal vias (0.3 mm drill, 0.5 mm pitch) tied to the inner-plane ground. Without the EP soldered the device will fail at modest power dissipation.
Place decoupling capacitors (0.1 uF X7R plus 10 uF bulk) within 3 mm of the VDD and VSS pins. The wide 1.6V-5.5V supply range means a single LDO downstream of a 24V industrial rail is acceptable. For battery applications, add a reverse-polarity Schottky diode on VDD to protect against swapped battery insertion.
The TOOL0 pin (P30) is a single-wire debug interface - never tie it directly to ground or supply, and avoid placing large capacitors directly on it. A weak pull-up (10-100 kohm) prevents spurious entry into debug mode at startup. Holding TOOL0 low during reset enters serial programming mode.
Keep analog AVREFP/AVREFM traces short and guarded by a ground pour to preserve ADC accuracy. Recommended: route digital signals (serial, debug) on opposite sides of the package from analog inputs. Source: Renesas RL78/G14 hardware manual layout recommendations.
