R5F21192SP#U0 - 16-Bit 20MHz R8C MCU | Renesas Electronics
N.º de pieza: R5F21192SP#U0 ✗ Fin de vidaR5F21192SP#U0 Descripción general
An R8C microcontroller is a single-chip embedded controller that combines a 16-bit CISC core, flash program memory, data memory, timers, serial interfaces, analog comparison functions, and I/O ports on one integrated circuit. The R8C core sits within Renesas's broader MCU hierarchy: R8C/Tiny Series CPU core, 16-bit microcontroller, embedded processing IC, and semiconductor. This combination makes the device suitable for compact control systems that require more computation than an 8-bit MCU without adopting a larger application-specific controller.
The R5F21192SP#U0 provides an 8 KB flash-memory configuration, a 20 MHz maximum operating frequency, and a 2.7 V to 5.5 V supply range. A distributor listing identifies a 512 x 8 internal memory organization, while the device description also identifies DataFlash capability and a four-channel comparator. These resources allow firmware, peripheral configuration, and application logic to share one compact package.
The device is fabricated using a high-performance silicon-gate CMOS process. The 20-pin PLSP0020JB-A LSSOP package supports conventional surface-mount assembly while providing a compact footprint for embedded products. The reported operating-temperature range is -20°C to 85°C. The R5F21192SP#U0 is presented by Renesas as a non-promotion product, so procurement planning should account for its non-promoted status and confirm availability before committing a new production design.
Typical design roles include compact industrial controllers, sensor-conditioning systems, embedded measurement products, serial-interface equipment, and low-to-moderate-speed appliance controls. The 8 KB flash capacity is most appropriate for firmware with focused control logic, while the 16-bit R8C architecture can simplify arithmetic and register organization compared with an 8-bit implementation.
PCB planning should preserve the LSSOP pad layout and route sensitive analog inputs away from switching nodes and high-current outputs. Decoupling capacitors should be placed close to the supply pins, while programming and serial-debug access must follow the device's recommended connection arrangement. Confirm pin assignments, clock requirements, and peripheral multiplexing in the manufacturer datasheet before final schematic release.
This page consolidates the exact orderable MPN, manufacturer product identity, verified technical attributes, sourcing context, package information, and design-oriented selection guidance into one engineering reference. It also distinguishes true drop-in packaging alternatives from related R8C devices that differ in memory capacity or other functional parameters.

Aplicaciones típicas
R5F21192SP#U0 es adecuado para 6 aplicacións: Compact Industrial Control, Sensor Conditioning and Monitoring, Embedded Measurement Instrument, Serial Interface Equipment, Appliance and Equipment Controller, Low-Power Embedded System.
Compact Industrial Control
The R5F21192SP#U0 fits compact supervisory controllers because its 16-bit R8C core operates at up to 20 MHz while retaining an 8 KB flash limit that suits focused control firmware. Place the 20-LSSOP device beside sensor-conditioning and interface circuitry, with the four available comparator channels used for threshold or protection functions. The 2.7 V to 5.5 V operating range supports 3.3 V and 5 V industrial-control architectures, while the stated -20°C to 85°C range covers many indoor equipment environments. Verify every pin assignment against the manufacturer datasheet and provide local decoupling close to the supply pins.
Recomendado
Sensor Conditioning and Monitoring
The R5F21192SP#U0 is appropriate for embedded sensing systems requiring a 16-bit processing core without a large package. Its four comparator channels can provide local threshold comparisons for sensor signals, while the 20 MHz R8C core can execute filtering, calibration, status handling, and data-transfer routines. The 2.7 V to 5.5 V range permits direct interface planning for 3.3 V sensors and logic, subject to individual peripheral specifications. Keep analog traces short and away from switching converters, and consult the pin-description table to select the correct comparator and I/O functions.
Recomendado
Embedded Measurement Instrument
The R5F21192SP#U0 can serve as the control processor in a compact measurement product combining a 16-bit R8C core with external precision converters. Its 8 KB flash memory is suitable for configuration tables, calibration coefficients, display handling, and concise measurement algorithms rather than large data logging workloads. Four comparator channels can support range detection or protection thresholds, and the 20-LSSOP package limits board area. Design the analog and digital sections carefully, provide stable references, and maintain separate return paths so switching activity does not degrade measurement accuracy.
Recomendado
Serial Interface Equipment
The R5F21192SP#U0 is well suited to compact protocol converters, configuration tools, and equipment-control modules where a 16-bit MCU can manage command parsing and multiple peripheral tasks. Its 20 MHz operating speed provides useful processing headroom, while the 8 KB flash capacity favors focused firmware with efficient code organization. The 2.7 V to 5.5 V range can simplify support for both 3.3 V and 5 V interface levels, although each transceiver must still be checked independently. Confirm the device's serial functions and pin multiplexing in the manufacturer documentation before finalizing the board.
Recomendado
Appliance and Equipment Controller
The R5F21192SP#U0 can implement the central logic of a compact appliance controller using its 16-bit R8C core, 8 KB flash, four comparator channels, and mixed 3.3 V or 5 V supply compatibility. The R8C architecture supports efficient control of timers, inputs, outputs, and communication tasks, while the 20-pin LSSOP package simplifies dense board layouts. Its -20°C to 85°C operating range suits many indoor products. Validate startup behavior, reset requirements, unused-pin treatment, and peripheral availability in the manufacturer datasheet before releasing a production design.
Recomendado
Low-Power Embedded System
The R5F21192SP#U0 can be considered for compact embedded systems that need a 16-bit core, 8 KB flash, and operation across 2.7 V to 5.5 V without adopting a larger package. It is particularly relevant to products combining several timed inputs, comparator-based sensing, and a modest serial-control requirement. The device's stated -20°C to 85°C range supports indoor operation, and its 20-pin LSSOP footprint can conserve board area. Review current consumption, peripheral sleep behavior, clock configuration, and wake-up sources in the manufacturer datasheet before establishing a power budget.

Notas de diseño
Follow the manufacturer PLSP0020JB-A land pattern exactly and confirm the lead pitch, span, and exposed-terminal treatment against the package drawing. Place the input and output capacitors immediately adjacent to the corresponding supply pins rather than routing supply current around the board. Maintain a compact return path beneath the device and isolate analog comparator inputs from high-current switching nodes.
Design the 2.7 V to 5.5 V supply rail with adequate startup margin, local high-frequency bypass, and a power source that remains within the manufacturer electrical limits during brownout conditions. Verify all peripheral operating conditions, clock settings, and I/O levels against VDD. If the system connects external signals, include appropriate protection and ensure idle levels do not force excess current through protection structures.
Do not treat a similar R8C-family package as proof of interchangeability. Confirm pin multiplexing, reset behavior, clock requirements, flash organization, serial functions, comparator channels, programming signals, and unused-pin requirements for the exact orderable suffix. The #U0 and #W4 suffixes indicate different supplied packing arrangements, so the programmed device configuration should remain the same when switching between them.
Route oscillator, programming, and communication signals away from analog-comparator inputs and switching-regulator connections. Use a continuous ground reference beneath the MCU where practical, keep comparator traces short, and avoid routing high-current load returns through the quiet analog area. If the board mixes sensitive measurement and digital control functions, use a deliberate partitioning strategy rather than relying only on software filtering.
