Integrated data flash simplifies data logging and parameter storage

Reliable operation with built-in safety features (WDT, LVD, POR)

Broad communications support including LIN for automotive and industrial networks

Mature ecosystem and long product life from Renesas improve supply stability

Simple migration path within RL78 and to newer Renesas families if needed

Packaging

Type: 64-LQFP (also referred to as 64-LFQFP), 10 x 10 mm body size

Material: Epoxy molding compound, copper alloy leadframe, lead-free matte tin plating (RoHS3 compliant)

Pin count and configuration: 64 gull-wing leads on four sides; typical lead pitch for LQFP64 is 0.5 mm; 48 pins are GPIO, remaining pins for power, ground, oscillator, debug, and peripherals

Mounting: Surface-mount technology (SMT)

Supplier device package: 64-LFQFP (10x10)

Package / Case references: 64-LFQFP (10x10), 64-LQFP

Tape & Reel: Suitable for automated assembly; delivered in TR for high-volume production

Thermal characteristics: No exposed pad; heat dissipates through leads and PCB copper. Use solid ground planes and thermal vias for better heat spreading. For exact thermal resistance values (e.g., ΘJA/ΘJC under JEDEC conditions), refer to the datasheet.

Electrical properties (package-related): Lead inductance and resistance consistent with LQFP; ESD and moisture sensitivity per Renesas specifications. For exact MSL level and ESD ratings, see datasheet.

Lifecycle

Status: Active and widely used in long-life RL78/G13 family; not near discontinuation based on typical Renesas lifecycle practices

Form/fit/function equivalents within RL78/G13 (same 64-LQFP footprint, verify pin compatibility and memory):

- R5F100Lx variants with different Flash sizes (e.g., ~96KB, ~128KB, ~256KB) and data flash options

- Temperature grade and packaging suffix variants (e.g., #V0, tray vs tape, different lead finishes). Confirm availability and exact suffix meanings in the datasheet.

Close alternatives in the RL78 family:

- RL78/G14 (enhanced features and performance, similar development model; check pin compatibility)

- RL78/G12 or RL78/G10 (smaller feature sets; not pin-compatible but similar software ecosystem)

Migration alternatives (not pin-compatible, redesign needed):

- Renesas RA2E1/RA2L1 (Arm Cortex-M23, ultra-low power, richer ecosystem)

- Renesas RX130/RX231 (higher performance 32-bit options)
