MB91350A Series

6. Various timers

• 4 channels of 16-bit reload timer (including 1 channel for REALOS) :

Internal clock frequency divider selectable from 2/8/32 (division by 64/128 selectable only for ch.3)

• 16-bit free-run timer : 1 channel

Output compare : 8 channels (MB91F353A/353A/352A/351A : 2 channels)

Input capture : 4 channels

• 16-bit PPG timer : 6 channels (MB91F353A/353A/352A/351A : 3 channels)

7. UART

• UART full duplex double buffer : 5 channels (MB91F353A/353A/352A/351A : 4 channels)

• Selectable parity on/off

• Asynchronous (start-stop synchronized) or CLK-synchronous communications selectable

• Built-in dedicated baud rate timer

• External clock can be used as transfer clock

• Assorted error detection functions (for parity, frame, and overrun errors)

• Support for 115 kbps

8. SIO

• 8-bit data serial transfer : 3 channels (MB91F353A/353A/352A/351A : 2 channels)

• Shift clock selectable from among three internal and one external

• Shift direction selectable (transfer from LSB or MSB)

9. Interrupt controller

• Total number of external interrupts : 17 (MB91F353A/353A/352A/351A : 9)

(One non-maskable interrupt pin and 16/8 ordinary interrupt pins that can be used for wakeup in stop mode.)

• Interrupts from internal peripherals

• Programmable priorities (16 levels) for all interrupts except the non-maskable interrupt

10. D/A converter

• 8-bit resolution : 3 channels (MB91F353A/353A/352A/351A : 2 channels)

11. A/D converter

• 10-bit resolution : 12 channels (MB91F353A/353A/352A/351A : 8 channels)

• Serial/parallel conversion type Conversion time : 1.48 µs

• Conversion mode (one shot conversion mode, continuous conversion mode)

• Activation source (software, external trigger, peripheral interrupt)

12. Other interval timer/counter

• 8/16-bit up/down counter

The MB91F353A/353A/352A/351A supports only an 8-bit up/down counter.

• 16-bit timer (U-TIMER) : 5 channels (MB91F353A/353A/352A/351A : 4 channels)

• Watch dog timer

13. I2C bus interface* (supports 400 kbps)

• 1 channel master/slave transmission and reception

• Arbitration and clock synchronization functions

14. I/O ports

• 3 V I/O ports

(5 V input is supported for those ports that are also used for external interrupts (16 ports, MB91F353A/353A/

352A/351A : 8 ports).

• Up to 126 ports (MB91F353A/353A/352A/351A : Up to 84 ports)
