FAQ
What is the maximum operating frequency of the R5F2L357ANFP#U1?
The R5F2L357ANFP#U1 supports a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 5 MHz to maintain timing integrity. This dual-frequency capability allows flexible power/performance trade-offs in battery-powered or wide-input-voltage designs, and the R5F2L357ANFP#U1 maintains full peripheral functionality across both ranges.
Does the R5F2L357ANFP#U1 include an integrated LCD driver?
Yes, the R5F2L357ANFP#U1 integrates a full LCD controller supporting up to 4 common outputs and 24 segment outputs, with selectable bias (1/2 or 1/3) and duty (static, 1/2, 1/3, 1/4). It includes dedicated VL1/VL2/VL4 pins and internal voltage multiplication - enabling direct connection to multiplexed LCD panels without external driver ICs or charge pumps. This feature is confirmed in the R8C/L35A Group specification and applies specifically to the R5F2L357ANFP#U1.
What debug interface does the R5F2L357ANFP#U1 support?
The R5F2L357ANFP#U1 supports on-chip debug via Renesas' single-wire debug (SWD) interface, compatible with E8/E8a debug emulators. This enables full real-time debugging, flash programming, register inspection, and breakpoint control without halting system operation. The R5F2L357ANFP#U1 also supports on-board flash rewrite during application execution using its background operation (BGO) function - a key capability for field firmware updates.
Is the R5F2L357ANFP#U1 pin-compatible with other R8C/L35x variants?
Yes, all R8C/L35A Group members, including R5F2L357ANFP#U1, R5F2L358ANFP#U1, and R5F2L35AANFP#U1, share identical 52-pin LQFP (PLQP0052JA-A) packaging and pinout. Differences are limited to internal memory size (48 KB vs. 64 KB vs. 96 KB program ROM) and data flash configuration - allowing hardware reuse across firmware variants without PCB redesign. This compatibility is explicitly defined in Tables 1.8 and 1.16 of the R8C/L35A Group datasheet.
What is the data flash endurance rating for the R5F2L357ANFP#U1?
The R5F2L357ANFP#U1 data flash is rated for 10,000 write/erase cycles, as specified in Table 1.7 of the R8C/L35A Group datasheet. This endurance applies to its 1 KB × 4 block architecture with background operation (BGO) support. The program ROM has a separate 1,000-cycle endurance rating. These values are measured under standard conditions (VCC = 2.7–5.5 V) and are guaranteed by Renesas for the R5F2L357ANFP#U1 device.
