The RX62T Group of high-performance microcontrollers with a maximum operating frequency of 100MHz are designed for motor control. They are equipped with multifunction timers (MTU, GPT), high-speed 12-bit A/D converter, and 10-bit A/D converter for facilitating motor control.The products also incorporate many safety features to comply with the IEC60730 safety standard for home appliances. In addition to a maximum of 256KB flash and 16KB RAM on-chip memory, they have a maximum of 32KB of on-chip flash memory for data storage. 64-pin to 112-pin packages are available.
RX62T has three high-speed A/D modules (12-bit A/Dx2units, 10-bit A/Dx1unit) and 20ch A/D conversions in total are possible. Each conversion time is 1μs.
3ch of simultaneous sampling is enabled only by one 12-bit A/D module.
7ch of simultaneous sampling is enabled by two 12-bit A/D modules and one 10-bit A/D module.
The continuous A/D conversion is simplified by the double data register newly installed in 12-bitA/D module.
RX62T has 6ch of programmable gain amplifiers.
o Each gain can be set independently.
RX62T has 6ch of analog comparators for 12-bit A/D inputs.
o Each comparator has 3 detection modes; "Higher than the reference voltage (CVREFH)", "Lower than the reference voltage (CVREFL)" and "Window" ("Higher than CVREFH" and "Lower than CVREFL").
o The reference voltage of comparator is selectable from the external source and the internal source.
o Each comparator has 2 input modes; "After the programmable gain amplifier" and " Before the programmable gain amplifier" .
o The result of comparison can control timer GPT.
Control contents: Counter Start /Stop /Clear, PWM control
RX62T has 16-bit timer x 16ch; MTU3 (100MHz operation,8ch), GPT(100MHz operation, 4ch), and CMT (4ch).
RX62T has 3ch of three-phase complementary PWM (MTU3x2ch, GPTx1ch) for controlling 3 motors.
MTU3 supports complementary PWM for which the load of software is less than MTU2.
GPT can independently control 4ch of single phase inverter with the complementary PWM.
GPT can independently control the right and the left dead-time of complementary PWM.
5V single power and 3.3V single power lineup. For the 3.3V products, analog power 5V supply setting is also available.
Lineup with CAN and without CAN.
Lineup of 0.5mm, 0.65mm and 0.8mm pitch PKG.
Memory-protection unit (MPU) is built in for all products.
