FAQ
What is the maximum operating frequency and core performance of the R5F51136ADLJ#2A?
The R5F51136ADLJ#2A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) using its 32-bit RX CPU core. Its five-stage pipeline, variable-length instruction set, and on-chip multiplier/divider enable deterministic real-time execution. The R5F51136ADLJ#2A achieves this performance while maintaining zero-wait-state access to both 256 KB flash and 32 KB SRAM at full speed.
Does the R5F51136ADLJ#2A support USB Battery Charging (BC) detection?
Yes, the R5F51136ADLJ#2A includes hardware-level USB Battery Charger Detection compliant with BC 1.2 specification. It identifies SDP (Standard Downstream Port), CDP (Charging Downstream Port), and DCP (Dedicated Charging Port) by analyzing D+ and D− line states during enumeration. This feature is implemented in the USB 2.0 full-speed host/function/OTG module and requires no firmware polling - the R5F51136ADLJ#2A reports charger type via dedicated status registers.
What LCD configurations does the R5F51136ADLJ#2A support?
The R5F51136ADLJ#2A integrates an LCD controller/driver supporting two segment-combination modes: 40 segment × 4 common or 36 segment × 8 common. It includes an on-chip voltage boost circuit enabling direct 5-V panel drive, contrast adjustment via software-controlled bias, and blinking functionality per segment group. The R5F51136ADLJ#2A drives these configurations without external bias generators or charge pumps.
How many capacitive touch channels does the R5F51136ADLJ#2A support, and what sensing methods are available?
The R5F51136ADLJ#2A supports 12 capacitive touch sensing channels (TS0–TS11) via its integrated Capacitive Touch Sensing Unit (CTSU). It supports both self-capacitance and mutual-capacitance measurement methods, with on-chip noise cancellation for robust operation in electrically noisy environments. Mutual-capacitance mode allows increased effective channel count with reduced pin usage - the R5F51136ADLJ#2A implements this using shared electrode routing and time-multiplexed scanning.
What low-power modes are available on the R5F51136ADLJ#2A, and what is the lowest supply current?
The R5F51136ADLJ#2A offers three low-power consumption modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it draws just 0.44 µA (typ.) while retaining SRAM content and enabling wake-up via RTC alarm, LPT match, or external interrupt. Recovery time from this state is 4.8 µs - the R5F51136ADLJ#2A achieves this ultra-low current using dedicated low-speed oscillators and selective clock gating across all peripheral domains.
