To all our customers
Regarding the change of names mentioned in the document, such as Mitsubishi Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.) Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names have in fact all been changed to Renesas Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been made to the contents of the document, and these changes do not constitute any alteration to the contents of the document itself. Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices and power devices.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 4570 Group is a 4-bit single-chip microcomputer designed with CMOS technology. Its CPU is that of the 4500 series using a simple, high-speed instruction set. The computer is equipped with a carrier wave output circuit for remote control, an 8-bit timer with a reload register, a 10-bit timer with a reload register, and an 8-bit timer with two reload registers. The various microcomputers in the 4570 Group include variations of the built-in memory size. The mask ROM version and One Time PROM version of 4570 Group are produced as shown in the table below. q System clock switch function .... f(XIN)/4 or not divided q Timers Timer 1... 10-bit timer with a reload register and carrier wave output auto-control function Timer 2 ........ 8-bit timer with a reload register Timer 3... 8-bit timer with two reload registers and carrier wave generation function q Interrupt .......... 4 sources q Power-on reset circuit q Watchdog timer ... 16 bits q Key-on wakeup function (Ports P0, P1, and P4, ON/OFF of port P4 can be switched) qPull-up transistor ..... (Ports P0, P1, and P4, ON/OFF of port P4 can be switched) q Voltage drop detection circuit q Clock generating circuit (ceramic resonance)
FEATURES
q Minimum instruction execution time When f(XIN) is selected for system clock ..... 1.5µs (f(XIN)=2.0 MHz, VDD=4.5 V to 5.5 V) When f(XIN)/4 is selected for system clock ........ 2.86µs (f(XIN)=4.2 MHz, VDD=2.0 V to 5.5 V) q Supply voltage ..... 2.5 V to 5.5 V (One Time PROM version) ...... 2.0 V to 5.5 V (Mask ROM version) Product M34570M4-XXXFP M34570M8-XXXFP M34570MD-XXXFP M34570E8FP M34570EDFP * *: Under development (Jan. 1999) ROM (PROM) size (! 10 bits) 4096 words 8192 words 16384 words 8192 words 16384 words
