E2E1019-27-Y3 ¡ Semiconductor ¡ Semiconductor MSM65352/65352B GENERAL DESCRIPTION ThisMSM65352/65352B version: Jan. 1998 Previous version: Nov. 1996 8-Bit Microcontroller with 4-Bit A/D Converter (with LCD Driver) The MSM65352 is a high performance 8-bit microcontroller that employs OKI original CPU core, the nX-8/50. The MSM65352 includes 8K-byte program memory, 256-byte data memory, LCD driver, timer, serial I/O and 4-bit A/D converter. Also available is the MSM65352B, which has four LCD outputs in place of four output ports. Also available are the MSM65P352 and MSM65P352B, which replace the on-chip program memory with one-time PROM. www.DataSheet4U.com FEATURES 2.7V to 5.5V –20°C to +70°C High speed side 0 to 10MHz (@VDD=5V± 10%) 0 to 5MHz (@VDD=2.7V to 5.5V) Low speed side 32.768kHz (@VDD=2.7V to 5.5V) Current consumption (Typ.): High speed side 5mA (@5MHz, VDD=3V) 20mA (@10MHz, VDD=5V) 1.5mA (@5MHz, VDD=3V, halt mode) Low speed side : 45mA (@32.768kHz, VDD=3V) 4mA (@VDD=3V, stop mode) Minimum instruction execution time : 400ns (@10MHz), 800ns (@5MHz) CPU core : 8-bit CPU core nX-8/50 General memory space : 8K-byte program memory Local memory space : 256-byte data memory + SFR LCD driver : 16 ¥ 4 (MSM65352), 20 ¥ 4 (MSM65352B) I/O port : 5 ports, 31 bits (MSM65352) 4 ports, 27 bits (MSM65352B) Input-output port : 2 ports ¥ 8 bits, 1 port ¥ 1 bit Input port : 1 port ¥ 1 bit 1 port ¥ 4 bits (Only for MSM65352) Output port : 1 port ¥ 8 bits, 1 port ¥ 1 bit...
