Renesas M37560EFDFP#U0

Overview

M37560EFDFP#U0 from Renesas is an 8-bit microcontroller with integrated LCD drive control (4 commons, 40 segments), 10-bit 8-channel ADC, dual 8-bit DACs, and PWM output-designed for embedded display control in consumer appliances. It features 60KB mask ROM, 2.5V–5.5V operation, and supports -40°C to +85°C extended temperature range in 100-pin QFP (100P6S-A) package.

For engineers reviewing the M37560EFDFP#U0 datasheet, M37560EFDFP#U0 pinout, M37560EFDFP#U0 application, or M37560EFDFP#U0 equivalent, key selection criteria include LCD bias/duty support (1/2, 1/3, 1/4), built-in charge pump, programmable pull-up resistors on P0–P2/P41–P47/P5/P6, and dual serial I/O channels (UART + clock-synchronized).

Technical Context

The M37560EFDFP#U0 implements a 740-family core with minimum instruction execution time of 0.4 µs at 10 MHz (A Version). It integrates a main clock circuit with built-in feedback resistor for ceramic resonator or quartz crystal use, plus a dedicated sub-clock circuit for 32 kHz crystal support.

Its peripheral set includes three 8-bit timers and two 16-bit timers, watchdog timer (14-bit), and memory-mapped I/O with 55 total I/O pins (8 outputs, 1 input, rest bidirectional). The LCD controller supports static and multiplexed drive with selectable bias and duty ratios, enabled by the internal charge pump.

FAQ

What is the maximum operating frequency supported by the M37560EFDFP#U0?

The M37560EFDFP#U0 supports a maximum main clock frequency of 10 MHz. At this frequency, its minimum instruction execution time is 0.4 microseconds (A Version). The device uses an external quartz crystal or ceramic resonator connected to XT1/XT2 pins, and its built-in feedback resistor eliminates the need for external biasing components. The M37560EFDFP#U0 also includes a dedicated 32.768 kHz sub-clock input for low-power RTC functions.

Does the M37560EFDFP#U0 include an internal voltage booster for LCD driving?

Yes, the M37560EFDFP#U0 integrates a built-in charge pump circuit that generates boosted voltages required for LCD biasing. This enables direct drive of 1/2- or 1/3-bias LCDs from a single 3.3 V or 5 V supply without external DC-DC converters. The M37560EFDFP#U0 supports 1/2, 1/3, and 1/4 duty cycles with up to 4 commons and 40 segments, making it suitable for segment-based displays in home appliances.

How many I/O pins does the M37560EFDFP#U0 provide, and which ports support pull-up resistors?

The M37560EFDFP#U0 provides 55 total I/O pins in its 100P6S-A package. Programmable pull-up resistors are available on ports P0 through P2, P41 through P47, P5, and P6 - covering 40+ configurable inputs. These internal pull-ups eliminate the need for external resistors in keypad, switch, or sensor interface designs. The M37560EFDFP#U0 also supports external interrupts on seven sources for responsive event handling.

What analog peripherals are integrated into the M37560EFDFP#U0?

The M37560EFDFP#U0 integrates a 10-bit successive approximation ADC with eight input channels, two independent 8-bit DACs, and an 8-bit PWM output channel. The ADC supports configurable sampling and conversion timing, while the DACs enable analog waveform generation (e.g., audio tones). The M37560EFDFP#U0's analog capabilities are designed for sensor interfacing, audio feedback, and precision control in consumer appliance UIs.

Is the M37560EFDFP#U0 pin-compatible with other members of the 7560 Group?

The M37560EFDFP#U0 shares the 100P6S-A package and pin configuration with several 7560 Group variants including M37560EFFP and M37560MFDXXXFP. Pinouts are documented in the "100P6S-A Pin Configuration" section of the official datasheet. However, differences in ROM type (OTP vs. mask), temperature grade, and minor peripheral enablement require verification of electrical and functional compatibility before substitution. Always consult the M37560EFDFP#U0-specific datasheet for final design validation.
