TMPR4955B

The TMPR4955B is designed as is a standard microcontroller of 64-bit RISC microprocessor TX49 family.

TMPR4955B has many features. The first one is TX49/H3 processor core. The second one is IEEE754 compatible single and double precision FPU. The third one is internal bus width is 64-bit, external bus width is 32-bit. The fourth one is power management would be internal: 1.5V and I/O: 3.3V. The fifth one is maximum operating frequency are 200 MHz, 300 MHz and 333 MHz. That are all the main features.

Some absolute maximum ratings of TMPR4955B  have been concluded into several points as follow. The first one is about its supply voltage (for I/O) which would be from -0.3 to 3.9V. The second one is about its supply voltage (for internal) which would be from -0.3 to 3.0V. The third one is about its input voltage which would be from -0.3 to Vcc + 0.3V. The fourth one is about its storage temperature which would be from -40 to +125°C. It should be noted that the absolute maximum ratings are rated values which must not be exceeded during operation, even for an instant.

And also some recommended operating conditions about TMPR4955B. The first one is about its supply voltage (for I/O) which would be min 3.1V and max 3.5V. The second one is about its supply voltage (for internal) which would be min 1.4V and max 1.6V. The third one is about its operating case temperature which would be from 0 to +70°C. It should be noted that the recommended operating conditions for a device are operating conditions under which it can be guaranteed that the device will operate as specified. If the device is used under operating conditions other than the recommended operating conditions (supply voltage, operating temperature range, specified AN and DC values etc.), malfunction may occur.
