Package type
64-pin LQFP package (0.5 mm pitch) and 64-pin QFP package (0.65 mm pitch)
|
|
High-speed operations at low voltage
Minimum execution time : 0.33µs (Automatically generates a 12 MHz main clock and a 48 MHz USB interface synchronization clock with an externally supplied 6 MHz clock and the internal PLL circuit.)
|
|
F²MC-8L CPU core
Instruction set that is optimum to the controllers
|
Multiplication and division instructions
|
|
16-bit arithmetic operations
|
|
branch instructions by bit testing
|
|
bit manipulation instructions, etc.
|
|
|
PLL clock control
The internal PLL clock circuit allows the use of low-speed clocks which are advantageous to noise characteristics.
(6 MHz externally-supplied clock : Internal system clock oscillated at 12 MHz)
|
|
Various timers
8-bit PWM timer (can be used as either 8-bit PWM timer x 2 channels or PPG timer x 1 channel)
Internal 21-bit timebase timer
|
|
Internal USB transceiver circuit (Compatible with high and low speeds)
|
|
USB function
Compliant to USB Protocol Revision 1.0
Support for both low and full speeds (selectable)
Allows four endpoints to be specified at maximum.
Types of transfer supported : control/interrupt/bulk/isochronous
Built-in DMAC (Maps the buffer for each endpoint on to the internal RAM to directly access the memory for function’s send and receive data.)
|
|
UART/serial interface
Built-in UART/SIO function (selectable by switching)
|
|
External interrupt
External interrupt (level detection x 8 channels)
Eight inputs are independent of one another and can also be used for resetting from low-power consumption mode (the L-level detection feature available).
|
|
Low power consumption (standby mode supported)
Stop mode (There is almost no current consumption since oscillation stops.)
Sleep mode (This mode stops the running CPU.)
|
|
A maximum of 53 general-purpose I/O ports
General-purpose I/O ports (CMOS) : 34
General-purpose output ports (CMOS) : 8
General-purpose I/O ports (Nch open drain) : 3
General-purpose input ports (CMOS 3.3 V input-compatible) : 8
|
|
Parallel ports
Also serve as eight of the general-purpose I/O ports (CMOS)
Interrupt function available
Allows asynchronous read and write by external signals
|
|
Power supply
Supply voltage : 3.0 to 5.5 V
