s/4.2 MHz

• Operating voltage: +2.2 V to +6.0 V, operating frequency: 1 MHz to 10 MHz
• Software-switchable instruction cycle (4 speeds) provides low voltage, low-power comsumption operation (clock

gear function)

• Backup voltage in stop mode (voltage required to maintain RAM data): Min. +1.5 V
• Bitwise selectable pull-up resistors for each I/O port
• One-time PROM products support (by programming data) the same option settings as mask ROM products (the

option settings are mask options for some products).

• Memory space: Max. 64 Kbytes
